The pion plays an outstanding role in nuclear physics as a generator of the nuclear force and as an important part of the nuclear many-body problem. At the same time, pion beams are used as probes to explore the nucleus and its interactions. As pion physics has matured over the years, a rich and diverse variety of phenomena has been uncovered. The aim of this book is to examine the underlying physical picture behind these phenomena in a systematic and coherent way. The authors emphasize the interplay between physical concepts and experimental facts more than the formal tools, which are presented in a series of appendices. The book is directed towards advanced students as well as research workers.

The proceedings reflect the recent experimental and theoretical progress in pion nuclear physics in topics like pionic atoms, pion absorption, charge exchange, (π, 2π), and others involving pions in nuclei using different probes, as electron photons or heavy ions. Related topics on chiral symmetry, low energy πN and (γ, π⁰) and quark degrees of freedom are also addressed.

Synthesizing the theoretical and experimental advances in pion-nucleon interactions over approximately the last twelve years, the authors offer here a timely account of the hadronic interactions of pions and nucleons and of the structure of nucleons. Because of the hadronic SU3 symmetry, the book also treats the structure of baryons in general, and so contains much material external to the specific field of pion-nucleon interactions. Thus the book's subject can be stated as the hadronic structure of baryons as illustrated particularly by pion-nucleon interaction. Following an introductory discussion of isotopic spin, the authors proceed to chapters that treat low energy pion scattering by nucleons and the photoproduction of pions; forward and fixed momentum transfer dispersion relations; analytic properties of scattering amplitudes; formation of nucleon resonances; symmetries and classification of particles and resonances; current algebra, sum rules, and superconvergence relations; scattering at higher energies; pion-nucleon dynamics; pion-nucleon inelastic scattering; and the form factors of the nucleon and the pion. Each chapter is followed by abundant references to the original literature. The level of the writing is suitable for students at the graduate level, and the presentation is even and self-contained. On balance, the authors have prepared a useful consolidation and review of this difficult and changing area of investigation. Originally published in 1973. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

"In the near future it is expected that one will have large enough fluxes of charged pions such that these mesons will make good nuclear probes. They interact strongly with the nucleus and yet do not form a compound state. Since pions form an isotopic triplet state allowing both single and double charge exchange scattering, new isobaric states can be investigated. In general the nucleus which is formed by [pi] + to [pi] double charge exchange is proton rich and has not been produced before. Another interesting aspect of pions at about 400 MeV energy is their predominant p-wave interaction with the nucleus and the ability of the pion to be totally absorbed, dumping 140 MeV into the nucleus at once.

The theoretical description of pion-nucleus interactions, specifically in the intermediate-energy region dominated?-excitation, is discussed. Attention is focused on the interaction with and propagation through the nucleus of pions and?'s. The approach followed basically consists of viewing the?-nucleus system, formed by pion excitation of a nucleon, as a doorway for the pion-nucleus reaction. Analysis of the interacting?-nucleus system then leads to new dynamical information summarized in a complex?-nucleus interaction potential. The associated nuclear medium corrections to? propagation, related in more conventional language to higher-order corrections in the pion optical potential, are so large as to demand consideration in quantitative studies of nuclear structure with pions. After a discussion of the basic scale parameters characterizing intermediate-energy pion-nucleus interactions, the author discusses the theoretical framework and the extraction of? interaction parameters from inclusive pion-nucleus cross sections. More detailed tests of the picture, such as elastic scattering angular distributions, are then discussed. Finally, some implications for intermediate-energy photoreactions are outlined. 11 figures.
