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.
The 14th RCNP OSAKA International Symposium on Nuclear Reaction Dynamics of Nucleon-Hadron Many Body System was held in Osaka from December 6 to 9, 1995. The symposium covered current topics from Nucleon Spins and Mesons in Nuclei to Quark Lepton Nuclear Physics. Thus it included the field of hadron/nuclear physics from sub-GeV to multi-GeV energy region, as well as recent activities and development at RCNP. It was also intended to be a kind of winter school for young researchers/graduate students.This proceedings consists of the invited talks and lectures presented by leading physicists in the field and short oral presentations.
A broad range of topics of current interest are discussed, from nuclear structure at the edge of stability to nuclear astrophysics and cosmic ray physics at the highest energies. Both the state of the art and basic background information are presented with a particular emphasis on interrelated research interests. The writers are all active scientists who enjoy the highest international reputation. They cover a range of problems of nuclear structure, in particular those concerning exotic nuclei and their decay modes, their relevance to nuclear reaction chains in stellar burning processes at various astrophysical sites, and as yet unsolved questions concerning the origin, acceleration mechanism, energy spectrum and elemental composition of high energy cosmic rays. Readership: Postgraduate physicists interested in the development of modern radioactive beam facilities, large array gamma ray and cosmic ray detectors, and new theoretical tools.
Hadronic atoms provide a unique laboratory for studying hadronic interactions essentially at threshold. This text is the first book-form exposition of hadronic atom theory with emphasis on recent developments, both theoretical and experimental. Since the underlying Hamiltonian is a non-self-adjoined operator, the theory goes beyond traditional quantum mechanics and this book covers topics that are often glossed over in standard texts on nuclear physics. The material contained here is intended for the advanced student and researcher in nuclear, atomic or elementary-particle physics. A good knowledge of quantum mechanics and familiarity with nuclear physics are presupposed. Contents: Theoretical Background: Hadronic Atoms OCo An Overview; Extended Quantum Mechanical Framework; Coulomb Wave Functions; Coulomb Propagator and Scattering Operators; Two-Potential Scattering Formalism; Bound States and Low-Energy Scattering; Atomic Spectrum; Gamow States and Completeness Problem; X-Ray Transition Rate; Computational Methods; Examples; Chiral Theory Primer; Comparison with Experiment: Two-Meson Atomic Bound States; Hadronic Hydrogen; Hadronic Deuterium; Hadronic Atoms with A OeN4. Readership: Graduate students and academics in nuclear, atomic, high-energy, computational, quantum and theoretical physics."
Nuclei and nuclear reactions offer a unique setting for investigating three (and in some cases even all four) of the fundamental forces in nature. Nuclei have been shown – mainly by performing scattering experiments with electrons, muons and neutrinos – to be extended objects with complex internal structures: constituent quarks; gluons, whose exchange binds the quarks together; sea-quarks, the ubiquitous virtual quark-antiquark pairs and last but not least, clouds of virtual mesons, surrounding an inner nuclear region, their exchange being the source of the nucleon-nucleon interaction. The interplay between the (mostly attractive) hadronic nucleon-nucleon interaction and the repulsive Coulomb force is responsible for the existence of nuclei; their degree of stability, expressed in the details and limits of the chart of nuclides; their rich structure and the variety of their interactions. Despite the impressive successes of the classical nuclear models and of ab-initio approaches, there is clearly no end in sight for either theoretical or experimental developments as shown e.g. by the recent need to introduce more sophisticated three-body interactions to account for an improved picture of nuclear structure and reactions. Yet, it turns out that the internal structure of the nucleons has comparatively little influence on the behavior of the nucleons in nuclei and nuclear physics – especially nuclear structure and reactions – is thus a field of science in its own right, without much recourse to subnuclear degrees of freedom. This book collects essential material that was presented in the form of lectures notes in nuclear physics courses for graduate students at the University of Cologne. It follows the course's approach, conveying the subject matter by combining experimental facts and experimental methods and tools with basic theoretical knowledge. Emphasis is placed on the importance of spin and orbital angular momentum (leading e.g. to applications in energy research, such as fusion with polarized nuclei) and on the operational definition of observables in nuclear physics. The end-of-chapter problems serve above all to elucidate and detail physical ideas that could not be presented in full detail in the main text. Readers are assumed to have a working knowledge of quantum mechanics and a basic grasp of both non-relativistic and relativistic kinematics; the latter in particular is a prerequisite for interpreting nuclear reactions and the connections to particle and high-energy physics.
The research program involved continuing analysis of Fermilab E-735, search for quark-gluon plasma (QGP) in {bar p}-p collisions; experiments on multi-fragmentation using reverse kinematics at the Bevalac; continuing study of target fragments produced in the interaction of copper with intermediate-energy heavy ions; and detector R & D for the STAR detector at RHIC.
