Book Description
This book provides the reader with a modern and comprehensive overview of nuclear polarization theory. The understanding of polarization phenomena greatly enriches data obtained from scattering and nuclear reactions by providing information on the interaction that can change spin orientation as well as important verification data for the study of nuclear structures and reaction mechanisms. The author methodically derives the polarization theory of nuclear reactions for various types of elastic scattering and two-body direct reactions between particles of different spin and unpolarized target nuclei with arbitrary spin, as well as the reactions between two polarized light particles and the polarization theory for photon beams. In addition, the polarization theories of relativistic nuclear reactions are rigorously covered in great scope and detail. A chapter on polarized particle transport theory presents the Monte-Carlo method for describing the transport of polarized particles and formalizes the polarized particle transport equation. Here, the author also illustrates a novel and concrete scheme for establishing a polarization nuclear database. Nuclear polarization is important not only for microscopic nuclear structure and reaction studies but also for nuclear engineering, applied nuclear physics, and medical physics. With the development of radioactive beam facilities and, on the theoretical side, the development of consistent microscopic nuclear reaction and structure theories, this book on the polarization theory of nuclear reactions serves as a timely source of reference for students and researchers alike.

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
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
The Fourth International Symposium on Polarization Phenomena in Nuclear Reactions took place from August 25 to 29, 1975, at the Swiss Federal Instituteof Technology in Zurich (ETHZ). Apart from the host institution the Symposium was also supported by the International Union of Pure and Applied Physics, the Swiss National Science Founda tion and the Swiss Physical Society. The program of the Symposium was set up with the advice of an International Program Committee with the following members: Prof. I. Ja. Barit, USSR Academy of Sciences, Moscow, USSR Prof. E. Baumgartner, University of Basel, Basel, Switzerland Prof. H. E. Conzett, Lawrence Berkeley Laboratory, Berkeley, USA Dr. W. Gruebler, Laboratorium fUr Kernphysik, ETH Zurich Prof. W. Haeberli, University of Wisconsin, Madison, USA Prof. S. S. Hanna, Stanford University, Stanford, USA Prof. J. McKee, University of Manitoba, Winnipeg, Canada Prof. G. C. Morrison, University of Birmingham, England Dr. G. G. Ohlsen, LASL, Las Alamos, USA Prof. J. Raynal, C. E. N. Saclay, France Dr. M. Simonius, Laboratorium fUr Kernphysik, ETH Zurich The Local Organizing Committee consisted of Dr. R. Balzer Dr. W. Grtiebler Dr. H. Jung Dr. V. Konig Prof. J. Lang Dr. M. Simonius Prof. W. G. Weitkamp (on leave from University of Washington, Seattle) It was generally felt that the Fourth Polarization Symposium should emphasize the importance of polarization measurements in the different fields of nuclear physics and explain the physical content of polariza tion phenomena."

Book Description
Methods of describing the polarization of particles of spin 1, such as the deuteron, are considered. The restrictions which the usual invariance requirements place upon the spin dependence of transition amplitudes are determined; no theory of nuclear interactions is presupposed. The polarization of the deuterons produced in the p + p yields pi(+) + d reaction is studied. Detailed assumptions concerning this reaction are not made, but limitations are put on the orbital angular momenta which should be valid if the energy is not too high. Elastic d-p scattering is suggested as a means of detection of this polarization, and the possibility of its use is explored.

Book Description
Spin physics is one of the most important and active areas of theoretical/experimental nuclear physics. In nuclear reactions, the observations of spin polarizations give important clues to the nuclear structures and reaction mechanism. For high energy nuclear physics, the polarized quark-parton distributions of the nucleon/nucleus are studied intensively. In the study of baryon structures and nuclear astrophysics, spin is an important observable through hadron reactions. The focus of these proceedings is on the spin-dependent phenomena in nuclear and hadronic reactions and related topics in nuclear and hadron physics. The main subjects covered are: spin polarization phenomena in nuclear and hadronic reactions; spin-dependent excitations in nuclei and spin observables; recent development in nuclear reaction theories; spin-dependent phenomena in fundamental processes; and related topics.
