Book Description
In the four years since the first Trieste Meeting on Spin and Polarization Dynamics in Nuclear and Particle Physics, considerable progress has been made both in the theoretical and experimental aspects of this field. The polarization phenomena have given rise to many more detailed and crucial tests which enhance our understanding of particle physics. New information can also be uncovered in the process of conducting the various tests. For this reason, considerable efforts have been put into the present and future accelerators to extend the experimental data to measure polarization asymmetries for both polarized targets and polarized scattered and produced particles. The 2nd Adriatico Research Conference held in January 1992 brought together both theorists and experimentalists who presented many new findings. These findings have been compiled into this compact volume to give a complete picture of the wide range of theoretical and experimental problems, difficulties, results, prospects and hopes which are at the core of particle physics studies today. It will be a useful guide for the present status of polarization phenomena and their fundamental implications.

Book Description
The success in the standard model and to the continuing research for a better understanding of the quantum chromodynamics has resulted in a great interest in spin physics among high energy and nuclear physics. Advances in accelerator technology have also spurred renewed interest in accelerating and storing highly aligned spin particles in synchrotrons and storage rings. The development of polarized ion sources and polarized electron sources have seen remarkable progress. With these advances in ion sources, there is a growing interest in the acceleration and maintenence of this polarization.This book is intended to be used as a graduate/senior undergraduate textbook in accelerator physics and sciences. The subject deals with acceleration and storage of polarized beams in high energy synchrotrons. The material covers the equation of motion for polarized beams in synchrotrons, spin depolarizing resonances, practical methods used in overcoming spin resonances, effects of spin rotators — called Siberian snakes — on the polarization vector, snake resonances, Sokolov-Ternov radiative polarization of electrons, and design principles of spin rotators. Experimental results of many polarized beam experiments are compared with theoretical analyses.Each chapter is also followed by exercises, which are intended to reinforce the concepts discussed, to derive useful formulae for applications, and to provide an introduction to some published literatures related to the polarized beam dynamics.

Book Description
One of the main challenges in nuclear and particle physics in the last 20 years has been to understand how the proton''s spin is built up from its quark and gluon constituents. Quark models generally predict that about 60% of the proton''s spin should be carried by the spin of the quarks inside, whereas high energy scattering experiments have shown that the quark spin contribution is small OCo only about 30%. This result has been the underlying motivation for about 1000 theoretical papers and a global program of dedicated spin experiments at BNL, CERN, DESY and Jefferson Laboratory to map the individual quark and gluon angular momentum contributions to the proton''s spin, which are now yielding exciting results. This book gives an overview of the present status of the field: what is new in the data and what can be expected in the next few years. The emphasis is on the main physical ideas and the interpretation of spin data. The interface between QCD spin physics and the famous axial U(1) problem of QCD (eta and etaprime meson physics) is also highlighted. Sample Chapter(s). Chapter 1: Introduction (159 KB). Contents: Spin Experiments and Data; Dispersion Relations and Spin Sum Rules; g 1 Spin Sum Rules; Fixed Poles; The Axial Anomaly, Gluon topology and g (0) A; Chiral Symmetry and Axial U(1) Dynamics; QCD Inspired Models of the Proton Spin Problem; The Spin-Flavour Structure of the Proton; QCD Fits to g 1 Data; Polarized Quark Distributions; Polarized Glue o g(x, Q 2 ); Transversity; Deeply Virtual Compton Scattering and Exclusive Processes; Polarized Photon Structure Functions; Conclusions and Open Questions: How Does the Proton Spin?. Readership: Academics, as well as physicists working on particle and nuclear physics at the interface of theory and experiment.

Book Description
Physics of Nuclei and Particles, Volume II explores the prevalent descriptive methods used in nuclear and particle physics, with emphasis on the phenomenological and model-based aspects. The interactions of nuclear particles are discussed, along with nuclear forces and potentials and scattering and reaction models employed in nuclear physics. The nuclear structure and models of the nucleus are also considered. Comprised of four chapters, this volume begins with a review of the characteristics of nucleons and other particles that play a role in nuclear interaction processes in order to gain further insight into the underlying physical problems. Neutron physics, antinucleons, deuteron physics, and two-body nuclear forces are highlighted, together with three- and four- nucleon systems and heavy-ion physics. The next three chapters deal with nuclear forces and potentials, as deduced from nuclear dynamics (scattering and polarization); scattering and reaction models used in nuclear physics; and nuclear models such as the shell model, models of deformed nuclei, and many-body self-consistent models. The book concludes with an analysis of the Brueckner-Bethe-Goldstone theory of nuclear matter. This book will be of interest to physicists.

Book Description
The measurement of spin-polarization observables in reactions of nuclei and particles is of great utility and advantage when the effects of single-spin sub-states are to be investigated. Indeed, the unpolarized differential cross-section encompasses the averaging over the spin states of the particles, and thus loses details of the interaction process. This introductory text combines, in a single volume, course-based lecture notes on spin physics and on polarized-ion sources with the aim of providing a concise yet self-contained starting point for newcomers to the field, as well as for lecturers in search of suitable material for their courses and seminars. A significant part of the book is devoted to introducing the formal theory—a description of polarization and of nuclear reactions with polarized particles. The remainder of the text describes the physical basis of methods and devices necessary to perform experiments with polarized particles and to measure polarization and polarization effects in nuclear reactions. The book concludes with a brief review of modern applications in medicine and fusion energy research. For reasons of conciseness and of the pedagogical aims of this volume, examples are mainly taken from low-energy installations such as tandem Van de Graaff laboratories, although the emphasis of present research is shifting to medium- and high-energy nuclear physics. Consequently, this volume is restricted to describing non-relativistic processes and focuses on the energy range from astrophysical energies (a few keV) to tens of MeV. It is further restricted to polarimetry of hadronic particles.

Book Description
In recent years, there has been considerable growth in research activities related to spin phenomena in high energy physics and their theoretical interpretations. It has become clear that the spin enigma is not to be considered separately but that it is strongly related to the quark-gluon structure of hadrons and their interaction dynamics.Research on spin phenomena has now attracted a significant following of experimental and theoretical physicists who meet regularly at symposiums on the topic.This book serves as an introduction to the spin puzzles at high energies. Its main focus is on spin effects in hadronic processes and the spin structure of nucleons.The volume will be very useful for graduate students and for those working in the field of polarization physics or interested in the various aspects of strong interaction dynamics. The only book on spin phenomena in high energy physics, it fulfils the great need for an introductory volume in this area of growing interest.

Book Description
This book allows the reader to understand the fundamentals of polarization phenomena in a general spin system, showing the polarizations to be indispensable information source of spin-dependent interactions. Particularly, the book describes polarization phenomena in nuclear scattering and reactions in detail, and explains how they provide information concerning spin-dependent interactions between the related particles. The concepts of polarization observables are explained, explicitly in the scattering of protons, deuterons and 7Li nuclei. In looking at deuteron and 7Li scattering, interactions induced by the virtual excitation of projectiles are examined in detail. Resonance reactions are investigated, focusing attention on the polarization of observables, which suggests that polarization phenomena can be used to determine the spin parity of the resonance. It is noted that in few-nucleon systems, the discrepancy between the values of polarization observables based on theoretical models and the corresponding values obtained through experimental data, is an important problem to be solved in the future. Solving this problem should provide new knowledge concerning the nuclear forces between nucleons.The author has chosen open-access publishing for this book to allow any interested person to study this branch of nuclear physics.

Book Description
This book consists of a series of lectures introducing what the author believes to be the theoretical minimum for the understanding of nuclear spin dynamics, the branch of physics underpinning magnetic resonance techniques such as NMR and MRI. Spin dynamics ultimately concern the study of the state and time evolution of systems made by a large collection of particles possessing spin, one of the most subtle and indeed fascinating concepts in relativistic quantum mechanics and whose understanding requires a mix of quantum mechanics, Hamiltonian dynamics and advanced mathematics. Written in the concise and direct style appropriate for university lectures, this book is addressed to both undergraduate and postgraduate students who are approaching magnetic resonance studies and want to reach the theoretical minimum required to understand the wider topic and its main applications. The book is suitable for researchers who work in the field of magnetic resonance and want to know more about its theoretical fundamentals. Finally, built as a complete set of 12 lectures and 4 workshops, the book can act as a solid reference to lecturers of magnetic resonance university modules. Trained in a world-leading research laboratory internationally recognised for its contributions to the NMR field, the author has a track record in theoretical and methodological developments of nuclear spin dynamics. In this book, he tries to merge his passion for the understanding of physics through its mathematical rendering with his personal quest for the elegance of a clean, clear and satisfactory explanation.
