A graduate-level one-volume textbook and reference work on the
structure and physics of atomic nuclei. Throughout this book the
underlying emphasis is on how a nucleus is constituted through the
interaction between the nucleons. The book is structured into three
parts: the first part contains a detailed treatment of the
two-nucleon force and of basic model-independent nuclear
properties; the second part discusses the experimental results of
nuclear models and their bases in fundamental theory; the third
part deals in some detail with alpha-decay and fission.
Results important for the general understanding of nuclear
structure have emerged from the study of the nuclei in the mass
region around the neutron-deficient and neutron-rich Zirconium
isotopes. This research report gives the proceedings of a workshop
which brought together about 70 experts in the area. Review papers
deal with the theoretical interpretation of the unusual properties
of these medium-mass nuclei, using the mean field approach, a
microscopic description, the interacting boson model and particle
rotor calculations. Papers also discuss experimental procedures for
studying nuclei far from stability and the possibility of complete
spectroscopy. The reviews are supplemented by short contributions
presenting very new results. Phenomena discussed include the
interplay between subshell effects and the strong proton-neutron
interaction in determining nuclear shape, the coexistence of
different nuclear shape and the occurrence of fast beta decay.
In diesem Buch werden zunachst die verschiedenen Typen von
Plasmen ausfuhrlich beschrieben: Gleichstrom-Entladung, kapazitive
und induktive Kopplung mit Radiofrequenz, die
magnetfeldunterstutzte Anregung mittels Heliconwellen; schliesslich
noch Ionenstrahlen. Breiten Raum nimmt dann die Plasmadiagnostik
ein, die in einem separaten Kapitel mit vier Methoden exemplarisch
vorgestellt wird. Daran anschliessend erfolgt eine umfassende
Darstellung der beiden modernen Verfahren Sputtern und
Trockenatzen, mit denen heute Oberflachen durch Beschichten und
gezieltes Abtragen auf vielfaltige Weise modifiziert werden.
Besondere Aufmerksamkeit wird reaktiven Verfahren und den dort
auftretenden Reaktionsmechanismen, aber auch der
Ionenstrahlmethode, gewidmet. Zahlreiche Anwendungsbeispiele sind
in den Text eingestreut. Fur die Neuauflage wurde das Buch
vollstandig neu bearbeitet und aktualisiert. Hinzu kamen neue
Kapitel uber Plasmadiagnostik und hochdichte sowie
induktiv-gekoppelte Plasmen."
The fundamental model of nuclear structure is the shell model.
However, its application has been limited to light nuclei (up to
the sd shell) or heavier nuclei with only a few valence nucleons
outside closed shells. Its application beyond these limits has been
prohibited so far by the large scale of the calculations involved.
For the description of nuclei beyond the sd shell having several
valence nucleons the introduction of collective models becomes
necessary. The first comprehensive phenomenological model of
nuclear structure was the geometric collective model of A. Bohr and
B.R. Mottelson. An alternative approach was proposed in 1974 by A.
Arima and F. Iachello, known as the Interacting Boson Model. This
model, which uses group theoretical techniques in the description
of nuclear collective properties, has the advantage of relative
simplicity, allowing for detailed calculations of the properties of
even medium and heavy nuclei which cannot be reached by the shell
model yet. Several extensions and generalizations of the model have
appeared over the last decade. Algebraic descriptions for the
effects of clustering, permanent octupole deformation, and giant
resonances have also been given. For the description of odd nuclei
the Interacting Boson-Fermion Model has been introduced, and
nuclear supersymmetries associated with it have been analysed. The
present text is designed to provide physicists with an accessible
introduction to the subject.
This self-contained introduction to compact star physics explains
important concepts from areas such as general relativity,
thermodynamics, statistical mechanics, and nuclear physics.
Containing many tested exercises, and written by an international
expert in the research field, the book provides important insights
on the basic concepts of compact stars, discusses white dwarfs,
neutron stars, quark stars and exotic compact stars. Included are
sections on astrophysical observations of compact stars, and
present and future terrestrial experiments related to compact stars
physics, as the study of exotic nuclei and relativistic heavy-ion
collisions. Major developments in the field such as the discovery
of massive neutron stars, and a discussion of the recent
gravitational wave measurement of a neutron star merger are also
presented. This book is ideal for graduate students and researchers
working on the physics of compact stars, general relativity and
nuclear physics.
This authoritative work enhances the material outlined in the first
volume of Concepts of Particle Physics, presenting it in far
greater detail and with a higher degree of sophistication. The
authors, both eminent physicists, provide an in-depth discussion of
the electromagnetic interaction, explore the accuracy of the quark
model by examining the excited states of baryons and mesons, and
consider many other topics.

The Working Group "0ffshore Nuclear Power Plants" was established
by the Commission of the European Communities in 1971. At that time
it appeared that the option offered by creating new sites offshore
should be explored. The present development of nuclear power has
not, however, reached the stage where offs hore siting can be
considered as a near or medium term proposition. The purpose of
this report is to summarize the state of the art for the provision
of floating or fixed structures, or man-made islands of the size
needed for the construction of nuclear and other power stations. It
describes the main factors which must be taken into account in the
design and location of such islands and provides an indication of
feasibility and cost for each design at the present time. It deals
mainly with the civil engineering problems and not other major
factors, such as the law of the sea, the rights of countries to
locate nuclear establishments off their coast, their safety,
security, the energy connection with the mainland, the marine
ecology, the logistics, etc. ; many of these problems are directly
related to the site and have major economic and political
implications. By studying application examples the Working Group
has occupied itself with these other factors.
The study which fonns the second volume of this series deals with
the interplay of groups and composite particle theory in nuclei.
Three main branches of ideas are de- veloped and linked with
composite particle theory: the pennutational structure of the
nuclear fermion system, the classification scheme based on the
orbital partition and the associated supennuitiplets, and the
representation in state space of geometric trans- fonnations in
classical phase space. One of the authors (p. K.) had the
opportunity to present some of the ideas under- lying this work at
the 15th Solvay Conference on Symmetry Properties of Nuclei in
1970. Since this time, the authors continued their joint effort to
decipher the conceptual struc- ture of composite particle theory in
tenns of groups and their representations. The pattern of
connections is fully developed in the present study. The
applications are carried to the points where the impact of group
theory may be recognized. The range of applications in our opinion
goes far beyond these points.
