The management and disposal of radioactive wastes are key international issues requiring a sound, fundamental scientific basis to insure public and environmental protection. Large quantities of existing nuclear waste must be treated to encapsulate the radioactivity in a form suitable for disposal. The treatment of this waste, due to its extreme diversity, presents tremendous engineering and scientific challenges. Geologic isolation of transuranic waste is the approach currently proposed by all nuclear countries for its final disposal. To be successful in this endeavor, it is necessary to understand the behavior of plutonium and the other actinides in relevant environmental media. Conceptual models for stored high level waste and waste repository systems present many sCientific difficulties due to their complexity and non-ideality. For example, much of the high level nuclear waste in the US is stored as alkaline concentrated electrolyte materials, where the chemistry of the actinides under such conditions is not well understood. This lack of understanding limits the successful separation and treatment of these wastes. Also, countries such as the US and Germany plan to dispose of actinide bearing wastes in geologic salt deposits. In this case, understanding the speciation and transport properties of actinides in brines is critical for confidence in repository performance and risk assessment activities. Many deep groundwaters underlying existing contaminated sites are also high in ionic strength. Until recently, the scientific basis for describing actinide chemistry in such systems was extremely limited."

Modern nuclear physics is a well developed branch of physical science, with wide-ranging applications of its results in engineering and industry. At the same time, the development of a consistent theory of nuclei and nuclear processes presents certain problems. It is well known that the most important aim of nuclear physics is the study of nuclear structure and the explanation of properties on the basis of the interaction between nucleons which constitute nuclei. Difficulties of a modern theory of the nucleus are caused by both an insufficient knowledge of nuclear interactions and the multi particle character of nuclear systems. Experimental data on nuclear interactions do not contradict the hypothesis of the pair character of nuclear forces. However, the absence of rigorous meth ods of calculations of many particle nuclear systems with strong interaction makes it necessary to use macroscopic nuclear models to describe particular nuclear properties. Nuclear models have been developed in different ways, and the models themselves have been modified and complicated. In spite of the visible discrepancy, different models of the nucleus significantly supple ment one another. The development of nuclear models has led to considerable progress in the understanding of atomic nuclei. The current results of theo retical nuclear physics are reported in numerous scientific papers. The most important and relevant experimental and theoretical results can be found in many monographs, the best of which are written by well-known experts in the field."

TIlls book is the result of an effort made by several members of the Euratom Neutron Radiography Working Group (NRWG) to produce a new, revised and enlarged edition of the Neutron Radiography Handbooldlj (NRH), written by members of the NRWG and published in 1981, just before the First World Conference on Neutron Radiography (WCNR) (1981). Members of the NRWG have contributed with many papers both to the first (1981)[2), as well as the second (1986)[3) and third (1989) [4) World Conference on Neutron Radiography (WCNR). They were also among the editors of the proceedings of those conferences (1982, 1987, 1990). The NRWG was constituted mainly for the purpose of promoting neutron radiography (NR) in the field of nuclear reactor fuel. Therefore the next topical publication of the NRWG were Reference Neutron Radiographs of Nuclear Reactor Fuel (1984)[5). The book on Collimators for y Thermal Neutron Radiograph 6/ written in 1987 by a member of the NRWG was another publication in the same series of books on NR. To the same series belongs the present book on Practical Neutron Radiography (PNR). It will be followed soon by another book written by the members of the NRWG: Neutron Radiography on Nitrocellulose Filmf71. The NRWG concentrated its interest in the past years on the problem of dimensional measurements from neutron radiographs. The results of the investigation of this problem were summarized in a special EUR report about the Neutron Radiography Working Group Test Program[8/ published in 1989.

With the appearance of Volume 3 of our series the review articles them selves can speak for the nature of the series. Our initial aim of charting the field of nuclear physics with some regularity and completeness is, hopefully, beginning to be established. We are greatly indebted to the willing coopera tion of many authors which has kept the series on schedule. By means of the "stream" technique on which our series is based - in which articles emerge from a flow of future articles at the convenience of the authors-the articles appear in this volume without any special coordination of topics. The topics range from the interaction of pions with nuclei to direct reactions in deformed nuclei. There is a great number of additional topics which the series hopes to include. Some of these are indicated by our list of future articles. Some have so far not appeared on our list because the topics have been reviewed re cently in other channels. Much of our series has originated from the sug gestions of our colleagues. We continue to welcome such aid and we continue to need, particularly, more suggestions about experimentalists who might write articles on experimental topics."

The present volume reaffirms nuclear physics as an experimental science since the authors are primarily experimentalists and since the treatment of the topics might be said to be "experimental." (This is no reflection on the theoretical competence of any of the authors.) The subject of high-spin phenomena in heavy nuclei has grown much beyond the idea of "backbending" which gave such an impetus to its study five years ago. It is a rich, new field to which Lieder and Ryde have contributed greatly. The article "Valence and Doorway Mechanisms in Resonance Neutron Capture" is, in contradistinction, an article pertaining to one of the oldest branches of nuclear physics-and it brings back one of our previous authors. The Doppler-shift method, reviewed by Alexander and Forster, is one of the important new experimental techniques that emerged in the previous decade. This review is intended, deliberately, to describe thoroughly a classic technique whose elegance epitomizes much of the fascination which nuclear physics techniques have held for a generation of scientists. This volume concludes the work on the Advances in Nuclear Physics series of one of the editors (M. Baranger), whose judgment and style characterize that which is best in the first ten volumes. Many of our readers and most of our authors will be grateful for the high standards which marked his contributions and which often elicited extra labor from the many authors of the series.

This book grew out of projects funded by the Kentucky Human ities Council in 1974 and 1975 and by the Environmental Protec tion Agency in 1976 and 1977. As a result of the generosity of these two agencies, I was able to study the logical, methodological, and ethical assumptions inherent in the decision to utilize nuclear fission for generating electricity. Since both grants gave me the opportunity to survey public policy-making, I discovered that there were critical lacunae in allegedly comprehensive analyses of various energy technologies. Ever since this discovery, one of my goals has been to fill one of these gaps by writing a well-docu men ted study of some neglected social and ethical questions regarding nuclear power. Although many assessments of atomic energy written by en vironmentalists are highly persuasive, they often also are overly emotive and question-begging. Sometimes they employ what seem to be correct ethical conclusions, but they do so largely in an in tuitive, rather than a closely-reasoned, manner. On the other hand, books and reports written by nuclear proponents, often under government contract, almost always ignore the social and ethical aspects of energy decision-making; they focus instead only on a purely scientific assessment of fission generation of electricity. What the energy debate needs, I believe, are more studies which aim at ethical analysis and which avoid unsubstantiated assertions. I hope that these essays are steps in that direction."

As we enter mid-19Bl, the Reagan administration is completing a review of U. s. nuclear waste management policy. Major revisions in the recently announced Carter administration policies are expected. Reagan is a strong supporter of civilian nuclear power and will probably encourage spent fuel reprocessing by the private sector. Meanwhile, the deep geologic disposal of defense nuclear waste in New Mexico moves ahead. In the coming months, discussion and debate of U. S. radioactive waste management policies will intensify in the Congress, in the technical community, and among environ mentalists and the public at large. An important element of the debate should be the scientific and technical issues of the safe disposal of radioactive wastes from both the civilian nuclear power fuel cycle and the defense fuel cycle, including naval pro propulsion programs and nuclear weapons production. The literature of waste management is voluminous, covering all aspects of the world-wide problem of safe disposal. The authors of this book have attempted to cri tically review this literature, selecting the more important reports to abstract. Our selection criteria were heavily influenced by considerations of policy issues and by our experiences in both the technical community and the regulatory environment. Our intent is to identify those reports we feel will contribute the most to the development of a national consensus on the safe disposal of existing and future nuclear wastes as yet another U. S. waste policy emerges in Washington."

This book is intended as an introductory exposition of those nuclear energy systems concepts which are characterized by an integrated utiliz ation of complementary nuclear processes. Basic to such systems is the notion of synergism, which herein implies the cooperative interaction of selected nuclear reactions and system components so as to provide overall advantages not possible otherwise. While the concept of nuclear energy synergism has in recent years become the focus of an increasing number of conferences, scientific papers, and institutional in-house reports, no text which encompasses the major topics of the subject at a conceptual and analytical level has appeared. It is our aim to present a systematic characterization of these emerging nuclear energy concepts suitable for the senior university student of nuclear science and engineering as well for the active pro fessional involved in nuclear energy systems planning and analysis. In addressing the subject of nuclear energy synergism we have become most conscious of the tension between realism and vision in nuclear energy technology. As developed here, our perception of nuclear energy synergism is firmly rooted in the present and then seeks to proceed toward a heightened degree of compatibility and efficacy based on an enhanced integration of relevant nuclear processes. It is our view that such conceptual considerations must assume a greater role in the emerging techological orientation of nuclear energy systems planning.

Most of this book was written before October 1973. Thus the statements concerning the energy crisis are now dated, but remain valid nevertheless. However, the term "energy crisis" is no longer the unusual new concept it was when the material was written; it is, rather, a commonplace expression for a condition with which we are all only too familiar. The purpose of this book is to point out that the science and technology of laser-induced nuclear fusion are an extraordinary subject, which in some way not yet completely clear can solve the problem of gaining a pollution-free and really inexhaustible supply of inexpensive energy from the heavy hydrogen (deuterium) atoms found in all terrestrial waters. The concept is very obvious and very simple: To heat solid deuterium or mixtures of deuterium and tritium (superheavy hydrogen) by laser pulses so rapidly that despite the resulting expansion and cooling there still take place so many nuclear fusion reactions tnat the energy produced is greater than the laser energy that had to be applied. Compression of the plasma by the laser radiation itself is a more sophisticated refinement of the process, but one which at the present stage of laser cechnology is needed for the rapid realization of a laser-fusion reactor for power generation. This concept of compression can also be applied to the development of completely safe reactors with controlled microexplosions of laser-compressed fissionable materials such as uranium and even boron, which fission completely safely into nonradioactive helium atoms.

This vOlume contains the invited and contributed papers pre sented at the American Nuclear Society (ANS) meeting on Decontamina tion and Decommissioning (D & D) of Nuclear Facilities, held Septem ber 16-20, 1979, in Sun Valley, Idaho. This was the first U. S. meeting of the ANS which addressed both of these important and related subjects. The meeting was attended by more than 400 engineers, scientists, laymen, and representatives of federal, state, and local governments, including participants from eleven foreign countries. The technical sessions included several sessions concentrating on ongoing D & D programs in the U. S. and abroad. In addition, "new ground" was broken in such areas as decommissioning costs and cost recovery, advanced programs on reactor coolant filtration, and other areas of continuing and increasing importance to the nuclear industry and to consumers. The dual sponsorship of the meeting (The ANS Reactor Operations Division and the Eastern Idaho Section of the ANS) helped spur a high quality program, a pleasant location, and a high degree of suc cess in technical interchange between the attendees. As guest speaker, we were honored to have Mr. Vince Boyer of Philadelphia Electric Company. Mr. Boyer is both a past chairman of the ANS Reactor Operations Division and a past president of the American Nuclear Society. His views on the nuclear industry and of its current status were informative and interesting."

This is the official record of the International Symposium on "The Role of Nuclear Engineering for an Uncertain Future" which was held on No vember 5 and 6, 1980, at Keidanren Hall in Tokyo, in connection with the 20th Anniversary of the Nuclear Engineering Department, Faculty of Engineering, University of Tokyo. Eight specialists from all over the world were invited to contribute papers to the symposium, and the professors of our Department presented a paper each. The Symposium was divided into seven sessions, chaired by profes sors of the Department according to their specialties. About 200 scientists attended the symposium, and some of them joined the discussions. The symposium was fruitful and very successful from every point of view, and highly evaluated by the attendants as well as by con cerned people outside. This success is due to the successful organization and good performance of the staff of this symposium, to whom I would like to express my grat itude. I also hope that these proceedings will be useful to the specialists who are concerned with the uncertain future of nuclear engineering as well as with the role of Universities in that future."

E. L. Zebroski During the 1970s, there was rapid growth of a philosophy that assumes that deindustrialization will result in an Elysian postindustrial society. This view is generally antitechnology; commonly in opposition to large-scale energy sources; and often supportive of high-cost, speculative, or at most, small-scale energy sources. The social and economic costs of policies which would lead to dein dustrialization are ignored or considered to be irrelevant. The development of civilian nuclear energy as a by-product of wartime developments also brings with it an association with the fear of nuclear weapons and with the repugnance for war in general. Many of these views and associations mingle to provide significant political constituencies. These have had consid erable impact on party platforms and elections. Also, another important aspect is the conservation viewpoint. This view--correctly--concerns the fact that in definite increase in per capita energy consumption, coupled with increasing U.S. and world populations, must at some point be restrained by limits on resources as well as by limits arising from environmental effects. All of these concerns have been subject to voluminous analysis, publications, and public discussion. They underlie one of the dominant social movements of the 1970s and 1980s. Indefinite exponential growth of energy production is neither possible nor de sirable."

Since the introduction of the first commercial inductively coupled plasma mass spectrometry (ICP-MS) instruments in 1983, the technique has gained rapid and wide acceptance in many analytical laboratories. There are now well over 400 instruments installed worldwide, which are being used in a range of disciplines for the analysis of geological, environmental, water, medical, biological, metallurgical, nuclear and industrial samples. Experience oflCP-MS in many laboratories is limited, and there is therefore a need for a handbook containing practical advice in addition to fundamental informa tion. Such a handbook would be useful not only to users new to the technique, but also to users with some experience who wish to expand their knowledge of the subject. Therefore we have written this book for users in a variety of fields with differing levels of experience and expertise. The first two chapters provide a brief history of ICP-MS and discussions of design concepts, ICP physical processes, and fundamental principles of instrument operation. Armed with this background knowledge, users will be better equipped to evaluate advantages and limitations of the technique. Detailed descriptions and information for instrumental components are provided in chapter 3. Subsequent chapters deal with the practical aspects of sample analysis by ICP-MS. Whether samples are to be analysed in liquid, solid .or gaseous form is always an important consideration, and there is a wide choice of sample introduction techniques."

1. Lyotropic Liquid Crystals The class of compounds known as thermotropic liquid crystals has been widely utilized in basic research and industry during recent years. The properties of these materials are such that on heating from the solid to the isotropic liquid state, phase transitions occur with the formation of one or more intermediate anisotropic liquids. The unique and sometimes startling properties of these liquid crystals are the properties of pure compounds. However, there exists a second class of substances known as lyotropic liquid crystals which obtain their anisotropic properties from the mixing of two or more components. One of the components is amphiphilic, containing a polar head group (generally ionic or zwitterionic) attached to one or more long-chain hydrocarbons; the second component is usually water. Lyotropic liquid crystals occur abundantly in nature, particularly in all living systems. As a consequence, a bright future seems assured for studies on such systems. Even now, many of the properties of these systems are poorly understood. It is the purpose of this review to consolidate the results obtained from nuclear magnetic resonance studies of such systems and to provide a coherent picture of the field. Probably the most familiar example of a lyotropic liquid crystal is soap in water. A common soap is sodium dodecylsulphate where an ionic group (sulphate) is attached to a hydrocarbon chain containing twelve carbons.

A IUTAM symposium on 'Waves in Liquid/Gas and Liquid/Vapor Two-Phase Systems' was held in Kyoto, Japan, 9-13 May 1994. Sixty-three scientists partici pated coming from ten countries, and forty-two lectures were presented. The list of participants and the program are included in this volume. The symposium was held in response to the request of the participants in the IUTAM symposium 'Adiabatic Waves in Liquid-Vapor System' held at Gottingen in 1989. At that time, the need for another symposium in about five years had been indicated by all the participants. This symposium intends to develop the subject of wave properties in more general liquid-gas two-phase systems. Topics in this symposium may be classified as (1) waves in liquid-gas bubble systems including interfacial effects, (2) waves in gas( vapor )-droplets systems, (3) waves in films or stratified systems, (4) waves with liquid-vapor transition, (5) waves with vapor-liquid transition, (6) wave propagation near the critical point and (7) waves with low pressure effect. As for topic (1), experiments, numerical simulations and analytical approaches to waves in bubly liquids were discussed. The importance of interbubble interactions through the liquid-field is now well established at least in terms of potential theory. There was also a progress concerning the well-posedness of governing equations for void waves. For pressure waves there were some new phenomena, such as bubble cluster formation and the occurrence of three-dimensional structures, in addition to a progress from more qualitative studies to quantitative ones."

Our volume in the annual review series on this occasion represents a departure from our usual practice in that it serves as a Festschrift for Eugene Wigner. Dr. Wigner has won many honours in his long, wide ranging and distinguished career spanning so many upheavals in civilized life. The editors and the authors, indeed the whole nuclear engineering community, will wish to join in a modest but further acknowledgement of the contributions he has made to nuclear engineering, not least to the morality and professionalism of nuclear engineering in a year that has raised such international concerns over safety. It suffices to make a bald statement of Eugene Wigner's life and times here, for the first article of the volume is a loving appreciation by his long-time colleague, Alvin Weinberg, an evaluation of his contribution historically during and after the Second World War but equally an account of the philosophy which Wigner provided to the burgeoning profession. Eugene Wigner was born 17th November, 1902 in Budapest, Hungary and his early schooling is described by Dr. Weinberg.

This book brings together various aspects of the nuclear fission phenomenon discovered by Hahn, Strassmann and Meitner almost 70 years ago. Beginning with an historical introduction the authors present various models to describe the fission process of hot nuclei as well as the spontaneous fission of cold nuclei and their isomers. The role of transport coefficients, like inertia and friction in fission dynamics is discussed. The effect of the nuclear shell structure on the fission probability and the mass and kinetic energy distributions of the fission fragments is presented. The fusion-fission process leading to the synthesis of new isotopes including super-heavy elements is described. The book will thus be useful for theoretical and experimental physicists, as well as for graduate and PhD students.

The search for flavored particles is one of the most;interesting topics in high energy physics. Many experimental groups are working on this subject, but the solution to many of the problems are still open. Therefore it seemed very useful that people interested in these problems can probe then in a discussion. This is the aim of this Europhysics Study Conference, which has been organized both as a conference and a workshop. The present experimental knowledge on branching ratios, life- times, cross sections and production mechanisms of flavored parti- cles has been presented in general talks and discussed in the morn- ing sessions, as well as the bases of the theoretical ideas and pre- dictions. The experimental methods: visual detectors, live targets, high resolution vertex detectors, special triggers of search on fla- vored particles, have been treated in the afternoon panels. These proceedings contain the talks and panel discussions with the exception of a few small contributions to the panels and talks by C. Baltay ("Search for charm and new flavors with bubble cham- bers"), G. Alteralle ("Lifetime of charm and new flavors"), P. Monacelli ("Results on charm production from a CERN Beam Dump exper- iment"), A. Capone ("Experimental study of same-sign dimunon events produced in neutrino and anti-neutrino beams").

All significant studies agree that aqueous corrosion continues to cost nations dearly in almost every area of technological endeavour. Over the past ten years, microcomputers have facilitated an explosion in the power of modelling as a technique in science and engineering. In corrosion they have enabled better understanding of polarization curves, they have transformed the scope of electrochemical impedance measurements and they have placed a large range of electrochemistry at the fingertips of the corrosion scientist. This book focuses on the models, rather than the computing, which have been made possible during the past decade. Aimed at all those with an interest in corrosion and its control, the book draws together the range of new modelling strands, suggests new avenues of approach and generates further momentum for improvements to corrosion management, whether by increased understanding of atomistic processes or by control of large plant.

The present volume in our annual review series reviews a wide range of developments, giving a broad interpretation to the "technology" of our title. Starting at the beginning, Science, we have the review of basic nuclear physics data of Walker and Weaver for reactor kinetics, particularly, there fore, delayed neutron data. In the search for better and better accuracy, it is being realized that this involves the closest scrutiny of fundamental data, given to us here from the Birmingham school. Associated with this review of data is the review from Italy by Professor Pacilio and his co workers of the theory of reactor kinetics in the stochastic form, and a valuable compilation of the theory underlying a wide range of practical techniques. Tending more to technology come the papers by Jervis, reviewing the application of digital computers to the control of large nuclear power stations as developed in both the united Kingdom and Canada, Pickman's review of the design of fuels for heavy water reactors, and the account by Ishi kawa and Inabe of the new Japanese Research Reactor Program, itself initially directed largely to fuel element studies. The balance of the volume is made up of more philoso phical contributions to the practicalities of nuclear power."

The Tenth International Workshop on "Laser Interaction and Related Plasma Phenomena" was held November 11-15, 1991, at the Naval Postgraduate School, Monterey, California. This conference joined physicists from 11 countries (Australia, Canada, China, France, Israel, Italy, Spain, Switzerland, united Kingdom, USA, and the USSR). This meeting was marked by the inauguration of the EDWARD TELLER MEDAL FOR ACHIEVEMENTS IN FUSION ENERGY. This medal served as a celebration of the tenth conference in the 22-year series and as an opportunity to honor one of the world's greatest physicists and a leading pioneer in this field: Edward Teller. Four medals were awarded in the inaugural ceremony. The first recipient of the medal was Nobel Laureate Nikolai G. Basov, who served for many years as Director of the LebedevPhysical Institute of the Academy of Sciences of the USSR. In his address to Edward Teller, Dr. Basov underlined that Dr. Teller was the first in history to produce an exothermal nuclear fusion reaction, the mechanism that may now lead to an inexhaustive, environmentally clean, and low cost energy source in the future. This goal, he stressed, becomes more crucial as the greenhouse effect may not permit burning of fossil fuels for much longer. Basov also reviewed events leading the International Quantum Electronics Conferences of 1963 where he disclosed the first publication on laser fusion and that of 1968 where he reported the first observation of fusion neutrons using a laser-irradiated target. The second recipient was John H.

The utilization of nuclear energy makes great demands on the knowledge of the engineers engaged in design work and calculations relating to construction in nuclear industry. Apart, of course, from nuclear reactors themselves, a great deal of nuclear experience is involved in the design and construction of radiotherapy centres, non destructive testing laboratories, particle accelerators, radioisotope laboratories and nuclear research plants. Whereas in the USA there appears to be no great difference in the methods of training personnel for fundamental or for applied science, European universities draw a sharp dividing line between the two fields. However, if we consider graduates solely from the point of view of their activities at their place of employment, two types of personnel can be distinguished: scientifically oriented research workers and those with a more technical and practical background who are looking for rational and rapid methods and solutions, even at some expense in terms of accuracy. The Engineering Compendium on Radiation Shielding endeavours to cover both approaches, the scientific and the technical. Volume I was devoted to the fundamental aspects of shielding, while Volumes II and III discuss its technology."

The European Community's programme on the decommissioning of nuclear ~wer plants has the prime objective of developing effective techniques and procedures for ensuring the protection of nan and his envirornnent aginst the potential hazards of nuclear ~wer plants that have been finally shut down. The Carrnission of the European Ccrrmunities organized this interna- tional conference to present results achieved during the past five years of the prograrme. It also provided an opportunity for discussions anongst experts fran Merriber States of the European Catmuni ty and participating SCl.en- tists fran outside the Ccrrmunity, on the issues and options for future research. The conference was limited to invited papers, presented by scien- tists involved in European Ccmnunity contract studies. The topics covered by the conference and in the proceedings are : characterization of the radioactivity associated with nuclear ~wer plants that have been finally shut dawn; implications of maintaining shut-down nuclear ~wer plants for long periods before disnantling; decontamination of metal and concrete surfaces for decommissioning purposes; dismantling of nuclear ~r plant cam~nents and structures; conditioning and packaging of the radioactive waste arising fran the dismantling; systems for remotely controlled decommissioning operations; aspects related to the classification of solid decommissioning waste, namely measurement of very low-level radioactivity and eValuation of radiological consequences; nuclear power plant design features facilitating decommissioning; experience with industrial-scale decommissioning operation. The proceedings also report the discussions on the papers as well as the results of two technical panels and of the concluding panel.

The European Community's research programme 'Management and Disposal of Radioactive Waste' has the prime objective of finding effective means for ensuring the safety of man and his environment against the potential hazards arising from such wastes. In 1980, the Commission of the European Communities held its first major meeting on the subject, and published the proceedings, discussions and results. This volume presents the proceedings of the second such conference, following the completion of a research and development programme in the five intervening years. The main topics discussed are: treatment and conditioning technology, testing and evaluation of waste forms and packages, geologic disposal, migration, and performance analysis of geologic isolation systems; representing an analysis of the latest results achieved by sustained collaboration of leading laboratories in Europe. Thus, all of the contributions are of a high standard from the major exponents in the field throughout the European Community.

This volume contains the proceedings of an International Conference on "Spin and Isospin in Nuclear Interactions," which was held in Telluride, Colorado USA, 11-15 March 1991. This was the fifth in a series of conferences held in Telluride every three years since 1979. In attendance at the conference were just under 100 participants, representing a total of 43 institutes from 12 different countries. In keeping with previous Telluride conferences, the role of spin and isospin degrees of freedom in both nuclear structure and nuclear interactions remained an important theme. Topics covered included new results on the spin- and isospin-dependent terms in the free and effective nucleon-nucleon interaction, Gamow-Teller excitations, charge and spin exchange with hadronic probes, and spin measurements with leptonic probes. Recent progress in the development of polarized sources, polarized targets, and po larimetry was also discussed, as were applications to neutrino physics and astrophysics. Whereas earlier Telluride conferences had dealt primarily with nucleon-nucleus inter actions, this meeting included extensive discussions on the role of spin and flavor in particle interactions, and on ways of "bridging the gap" between concepts usually as sociated with particle physics and the domain of more conventional nuclear physics. The conference consisted of morning and evening scientific sessions, leaving the afternoons free for informal discussions, recreation, and enjoyment of the scenic beauty of the Telluride area. In addition to the invited talks, time was allotted for contributed talks on new results."
