Book Description
This volume contains the proceedings of the "International Conference on Spin Excitations in Nuclei" held in Telluride, Colo rado, March 25-27, 1982. The motivation for the conference was, in a large part due to the recent development of new variable energy accelerators which produce high quality beams of electrons, protons, and pions that are providing the first precise information on spin excitations in nuclei over a large range of spin and mass. In the past such data had been restricted primarily to light nuclei and were generally resolution limited. Perhaps, the most exciting new result has been the clear observation of the elusive spin-dipole strength (Gamow Teller and Ml) in medium and heavy mass nuclei through the use of the (p,n) and (p,p') reactions at or near zero degrees with 100-200 MeV incident protons. Energy dependence in the isovector parts of the nucleon-nucleon interaction make the 100-200 MeV energy region particularly appropriate for such studies. The clean data from (e,e'), ('IT,'IT'), (p,p'), and (p,n) on high spin "stretched" states which have particularly simple structure has also been quite impor tant. The recent results contain important new information on the nature of the spin dependent forces in nuclei. These in turn are inherently related to the properties of the nuclear mesonic field and the underlying quantum chromodynamics.

Book Description
The three articles of the present volume pertain to very different subjects, all ofconsiderable current interest. The first reviews the fascinating history ofthe search for nucleon substructure in the nucleus using the strength ofGamow– Teller excitations. The second deals with deep inelastic lepton scattering as a probe ofthe non-perturbative structure of the nucleon. The third describes the present state ofaffairs for muon catalyzed fusion, an application of nuclear physics which many new experiments have helped to elucidate. This volume certainly illustrates the broad range ofphysics within our field. The article on Nucleon Charge-Exchange Reactions at Intermediate Energy, by Parker Alford and Brian Spicer, reviews recent data which has clarified one of the greatest puzzles of nuclear physics during the past two decades, namely, the “missing strength” in Gamow–Teller (GT) transitions. The nucleon-nucleon interaction contains a GT component which has a low-lying giant resonance. The integrated GT strength is subject to a GT sum rule. Early experiments with (n,p) charge exchange reactions found only about half of the strength, required by the sum rule, in the vicinity of the giant resonance. At the time, new theoretical ideas suggested that the GT strength was especially sensitive to renormalization from effects pertaining to nucleon substructure, particularly the delta excitation of the nucleon in the nucleus.

Book Description
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.

Book Description
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.

Book Description
The XV Workshop on Nuclear Physics was devoted to the study of nucleon models, nuclear structure, nuclear reactions as well as exotic forms of nuclear matter. In particular, studies of the link between gauge theories and nuclear decay were presented. Nuclear reactions at intermediate energies, highly excited nuclear states, high spin and statistical features of the nucleus were also issues of interest which were analyzed during the Workshop. Avid researchers in this field will find this collection of papers enlightening in the analyses made and almost all-encompassing in its wide exploration of the many pertinent issues which stand at the core of nuclear physics today.

Book Description
This is the proceedings of the symposium on Frontiers of Nuclear Structure Physics which was held from March 2-5, 1994, in honor of Akito Arima. Nuclear structure physics is approaching a new era owing to various recent developments such as radioactive nuclear beams, multiple gamma-ray detectors, massive parallel computers, etc. In the near future RHIC, CEBAF and other facilities will further extend the horizons of the field and this meeting offered a look at these exciting possibilities ahead. Topics discussed included (i) new trends in shell model, (ii) electroweak interactions in nuclei, (iii) unstable nuclei, (iv) Interacting Boson Model, (v) proton-neutron degrees of freedom in nuclear collectivity, (vi) quarks in hadrons and nuclei, (vii) nuclear astrophysics, (viii) nuclear and atomic clusters.
