This book summarizes the considerable progress recently achieved in the understanding of nucleon and nuclear structure by using high energy electrons as a probe. A collection of papers discusses in detail the new frontiers of this field. Experimental and theoretical articles cover topics such as the structure of the nucleon, nucleon distributions, many-body correlations, non-nucleonic degrees of freedom and few-body systems. This book is an up-to-date introduction to the research planned with continuous beam electron accelerators.

The 1985 Summer School on Nuclear Dynamics, organized by the Nuclear Physics Division of the Netherlands' Physical Society, was the sixth in a series that started in 1963. This year's topic has been nuclear dynamics rather than nuclear structure as in the foregoing years. This change reflects a shift in focus to nuclear processes at higher energy, or, more generally, to nuclear processes under less traditional circumstances. For many years nuclear physics has been restricted to the domain of the ground state and excited states of low energy. The boundaries between nuclear physics and high-energy physics are rapidly disappearing, however, and the future will presumably show that the two fields of research will contribute to one another. With the advent of a new generation of heavy-ion and electron accelerators research activities on various new aspects of nuclear dynamics over a wide range of energies have become possible. This research focuses in particular on nonnucleonic degrees of freedom and on nuclear matter under extreme conditions, which require the explicit introduction of quarks into the description of nuclear reactions. Mean-field formulations are no longer adequate for the description of nucleus nucleus collisions at high nucleon energies as the nucleon-nucleon collisions begin to dominate. Novel dynamical theories are being developed, such as those based upon the Boltzmann equation or hadrodynamic models. The vitality of nuclear physics was clearly demonstrated by the enthusiastic lecturers at this summer school. They presented a series of clear and thorough courses on the subjects above.

Scattering of high-energy electrons from nuclear and nucleon targets essentially provides a microscope for examining the structure of these tiny objects. This 2001 book examines the motivation for electron scattering, develops the theoretical analysis of the process and summarises present experimental capabilities. Suitable for advanced undergraduates, graduates and researchers.

International Conference on Nuclear Structure presents the status of research in nuclear structure. This book covers the more traditional topics, including giant resonances, high-spin states, current and momentum distributions in nuclei, and single particle and collective excitations at low excitation energy. Organized into eight sessions, this book begins with an overview of the experiments with low momentum antiprotons. This text then examines the interaction between two free nucleons, which can be described by their scattering matrix, by their scattering cross sections, or by relativistic or nonrelativistic potentials. Other sessions consider the results on neutron-hole states in the Zr, Sn, and Pb region from pic-up measurements. This book discusses as well the progress in the investigation of high-spin magnetic observables in medium and heavy nuclei. The final chapter deals with the methods of performing measurements of neutrino masses. This book is a valuable resource for nuclear physicists, scientists, and research workers.

Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.

The rms charge radius of /sup 3/He was measured to be 1.90 +- 0.05 fm by means of low momentum transfer electron scattering at the National Bureau of Standards. A report to be submitted for publication is being prepared. In July a fifth (e, e') spectrum was measured at NBS for the /sup 20/Ne giant resonance region. The analysis of /sup 20/Ne data without the need of an arbitrary quasielastic continuum contribution is completed. The region between the neutron and proton thresholds is dominantly of electric quadrupole character, and that above the proton threshold of electric dipole character. Form factors were extracted. Magnetic elastic scattering was measured for /sup 25/Mg at the Bates Electron Linear Accelerator of Middleton, Massachusetts. A fixed scattering angle of 160/sup 0/, and electron energies between 140 and 270 MeV were used. The ground state M5 form factors were extracted after corrections were made for Coulomb scattering contributions at 160/sup 0/. Forward-angle data taken at Mainz, Germany in a U. Mass.-Mainz collaborative experiment were used in making these corrections and in extracting C2, and for the first time, C4 moments. At the I.K.O. laboratory of Amsterdam, The Netherlands, M1 and some M3 form factor points were measured. Thus information on form factors of all possible multipoles was obtained.
