These lectures review the recently developed vector coherent state
method. The book is an excellent introduction to the field because
of the many examples treated in detail, in particular those from
nuclear and particle physics. These calculations will be welcomed
by researchers and graduate students. The author reviews the
concepts of coherent states of the Heisenberg algebra and shows
then that the vector coherent state method maps the higher symmetry
algebra into an n-dimensional harmonic oscillator algebra coupled
with a simple intrinsic symmetry algebra. The formulation involves
some vector (or analogous higher symmetry) coupling of the
intrinsic algebra with the n-dimensional oscillator algebra,
leading to matrix representations and Wigner coefficients of the
higher symmetry algebra expressed in terms of simple calculable
functions and recoupling coefficients for the simpler intrinsic
algebra.
Charge density analysis of materials provides a firm basis for the
evaluation of the properties of materials. The design and
engineering of a new combination of metals requires a firm
knowledge of intermolecular features. Recent advances in technology
and high-speed computation have made the crystal X-ray diffraction
technique a unique tool for the determination of charge density
distribution in molecular crystal. Methods have been developed to
make experimental probes capable of unraveling the features of
charge densities in the intra- and inter-molecular regions of
crystal structures. In Metal and Alloy Bonding - An Experimental
Analysis, the structural details of materials are elucidated with
the X-ray diffraction technique. Analyses of the charge density and
the local and average structure are given to reveal the structural
properties of technologically important materials. Readers will
gain a new understanding of the local and average structure of
existing materials. The electron density, bonding, and charge
transfer studies in Metal and Alloy Bonding - An Experimental
Analysis contain useful information for researchers in the fields
of physics, chemistry, materials science, and metallurgy. The
properties described in these studies can contribute to the
successful engineering of these technologically important
materials.
The fifteenth European Conference on Few-Body Problems in Physics
has taken place during the week of June 5th to 9th, in the lovely
village of Peniscola, approximately midway between Barcelona and
Valencia on the Mediterranean coast. This conference continues the
tradition initiated in 1972 at Budapest, where the first conference
took place, and followed in Graz (1973), Tiibingen (1975), Vlieland
(1976), Uppsala (1977), Dubna (1979), Sesimbra (1980), Fer- rara
(1981), Tbilisi (1984), Fontevraud (1987), Uzhgorod (1990), Elba
(1991) and Amsterdam (1993). During this week, a total of one
hundred and fifty one scientist were exchang- ing their knowledge
and initiatives in this broad field of Few-Body Physics. Even if
the name of the conference restricts its domain to Europe, there
has been an important participation of scientists from non-European
countries. A conference with more than twenty years of tradition is
already an au- tonomous being, with a noticeable inertia.
Nevertheless, it is a reasonable thought to bend this inertia
trying to introduce some innovation, of course, without any damage
to the basic structure and objectives of the conference.
In this volume seven leading theoreticians and experimenters review
the origin of the asymmetry of matter and antimatter in the Big
Bang, solar neutrinos, the physics of enormous densities and
temperatures in stars and of immense magnetic fields around
collapsed stars, strong electric fields in heavy ion collisions,
and the extreme conditions in quark-gluon plasmas. The articles
address nuclear and particle physicists, especially graduate
students, but also astrophysicists and cosmologists, since they
have to deal with events under the extreme physical conditions
discussed here.
In the present edition, a number of new features have been added.
First of all, a number of typographical errors that had crept into
the text have been corrected. More importantly, a number of new
examples, figures and smaller sections have been added. In
evaluating the two-body matrix elements which characterize the
residual interaction, attention has been paid to the multipole
expansion and insight into the importance of various multipoles is
presented. The 18 example of 0 is now worked out for all the
different angular momentum states in the section on configuration
mixing. Some additional comments on how to determine one- and
two-body matrix elements in jn configurations, on isospin and the
application of isospin to the study of light odd-odd nuclei are
included. In Chap. 3, a small section on the present use of
large-scale shell model calculations and a section on experimental
tests of how a nucleon actually moves inside the nucleus (using
electromagnetic probing of nucleonic motion) has been added. In
Chap. 4, some recent applications of the study of quadrupole motion
in jn particle systems (with reference to the Po, Rn, Ra nuclei)
are presented. In the discussion of magnetic dipole moments, the
effects and importance of collective admixtures are pointed out and
discussed. In Chap. 5, some small additions relating to the
particle-hole conjugation and to the basic Hartree-Fock theory have
been made. In Chap.
Scattering theory is of interest to physicists and to chemists and
has a wide variety of applications, but it also presents a
considerable challenge to mathematicians, including numerical
analysts. Within the Schroedinger picture in this volume are
collected the various theoretical and mathematical treatments of
scattering together with a host of reviews of its applications to
atomic and nuclear physics, to surface physics and chemistry, for
example trapping of atoms on surfaces, and to amorphous condensed
systems. The reviews give a concise and pedagogically useful
presentation of the state of the art, and may serve as
introductions for newcomers, in particular for graduate students.
This book introduces systematically the operator method for the
solution of the Schroedinger equation. This method permits to
describe the states of quantum systems in the entire range of
parameters of Hamiltonian with a predefined accuracy. The operator
method is unique compared with other non-perturbative methods due
to its ability to deliver in zeroth approximation the uniformly
suitable estimate for both ground and excited states of quantum
system. The method has been generalized for the application to
quantum statistics and quantum field theory. In this book, the
numerous applications of operator method for various physical
systems are demonstrated. Simple models are used to illustrate the
basic principles of the method which are further used for the
solution of complex problems of quantum theory for many-particle
systems. The results obtained are supplemented by numerical
calculations, presented as tables and figures.
This book begins with a very readable survey "The Sun Today" by
J.-C. Pecker. It is followed by thorough reviews from leading
experts covering theory and observations. The focus shifts from the
solar core, studied via neutrino emissions and helioseismology,
through the interface regions where it is believed the large-scale
magnetic fields are generated, to the corona, where most of the
high temperature phenomena characteristic of this region may be
studied directly. As energetic particles play such a vigorous role
in this part of the sun, a separate session was devoted to their
transport and storage in the corona.
Measuring the hydrogen content in materials is important both for
research and for various applications in material and surface
sciences, such as hydrogen embrittlement of steel, controlled
thermonuclear reaction first wall studies, and changed material
properties caused by dissolved hydrogen. Hydrogen is the most
difficult atomic species to analyze by traditional methods, but
nuclear physics methods are particularly suited for this purpose.
President of the Uzbek SSR Academy of Sciences P.K. Khabibullaev
and Professor B.G. Skorodumov discuss in this book the
characteristics of these methods, such as lower detection limits,
selectivity in respect to different isotopes, accuracy, depth
resolution and maximum detection depth. Examples of applications
that are dealt with include the determination of material humidity,
the dating of objects, the study of hydrogen diffusion including
non-stationary processes, and the investigation of changes in
material properties like superconductivity, plasticity and
electrical properties due to contamination by hydrogen.
Written in a pedagogical way, the articles in this book address
graduate students as well as researchers and are well suited for
seminar work. Subjects at the forefront of nuclear research,
bordering other areas of many-particle physics, such as electron
scattering at different energy scales, new physics with radioactive
beams, multifragmentation, relativistic nuclear physics, high spin
nuclear problems, chaos, the role of the continuum in nuclear
physics or recent calculations with the shell model are presented.
It is felt that the topics treated in this book address the main
future lines of development of nuclear physics.
In this volume, experimentalists and theoreticians discuss which
experiments and calculations are needed to make significant
progress in the field and also how experiments and theoretical
descriptions can be compared. The topics treated are the
electromagnetic production of Goldstone bosons, pion--pion and
pion--nucleon interactions, hadron polarizability and form factors.
The book provides a review of the hadronic final state measurements
at HERA in deep inelastic scattering. It covers general event
properties, particle spectra, heavy flavours, jets, event shape
measurements, QCD instantons and small-x physics. The emphasis is
on experimental results, providing quick access to the data
(complete up to fall 1997) for reference. The results are discussed
in the context of QCD.
This volume is published in honor of Friedrich Hund's 100th
birthday. It is a modern review on matter at high densities and
pressures in astrophysics from Hund's early contribution to
present-day ideas. The relation between the equation of state and
the structure of compact cosmic objects is discussed, and two main
contributions deal with the equation of state of baryonic matter at
nuclear densities and with the numerical solution of the general
relativistic field equations for non-rotating and rapidly rotating
neutron stars. In a final chapter the present state of
asteroseismology is presented as a tool to explore the interior of
cosmic objects by analyzing the observed free oscillations of the
Earth, the Sun, and white dwarf stars.
Rasmus Brogaard's thesis digs into the fundamental issue of how the
shape of a molecule relates to its photochemical reactivity. This
relation is drastically different from that of ground-state
chemistry, since lifetimes of excited states are often comparable
to or even shorter than the time scales of conformational changes.
Combining theoretical and experimental efforts in femto-second
time-resolved photoionization Rasmus Brogaard finds that a
requirement for an efficient photochemical reaction is the
prearrangement of the constituents in a reactive conformation.
Furthermore, he is able to show that by exploiting a strong ionic
interaction between two chromophores, a coherent molecular motion
can be induced and probed in real-time. This way of using
bichromophoric interactions provides a promising strategy for
future research on conformational dynamics.

CP violation is an intriguing and elusive subject, and current
knowledge of it remains limited, on both the experimental and
theoretical levels. Researchers lack a fundamental understanding of
its origin, and this is all the more important because CP violation
is related to the generation problem and mass problem, two of the
basic open questions in particle physics. This book provides
beginning researchers with a self-contained introduction to the
subject, starting at an elementary level and taking the reader to
the forefront of current research.
