Book Description
Proposed forms for nuclear momentum distributions are investigated. Calculations of (p, p') reactions using those forms are done in a PWIA at angles where the quasielastic peak is seen and also at back angles. The parameters used are derived from (e, e') data, where the nuclear momenta probed overlap with those of the low angle (p, p') experiment. Although there is reasonable agreement for the (p, p') data at 180°, the inclusion of distortion necessitates a different parameter set to obtain agreement for the quasifree process. It is concluded that the (p, p') reaction cannot be readily understood with a simple momentum distribution.

Book Description
This volume presents the proceedings of the Workshop on Momentum Distributions held on October 24 to 26, 1988 at Argonne National Laboratory. This workshop was motivated by the enormous progress within the past few years in both experimental and theoretical studies of momentum distributions, by the growing recognition of the importance of momentum distributions to the characterization of quantum many-body systems, and especially by the realization that momentum distribution studies have much in common across the entire range of modern physics. Accordingly, the workshop was unique in that it brought together researchers in nuclear physics, electronic systems, quantum fluids and solids, and particle physics to address the common elements of momentum distribution studies. The topics dis cussed in the workshop spanned more than ten orders of magnitude range in charac teristic energy scales. The workshop included an extraordinary variety of interactions from Coulombic to hard core repulsive, from non-relativistic to extreme relativistic.

Book Description
This volume contains lectures on several topics of great current relevance in strong interaction physics. The lectures were presented at the 13th Annual HUGS at CEBAF summer school to an audience of advanced PhD students, both theorists and experimentalists. They reflect the current trend of nuclear physics research, shaped to a large extent by the experimental progress allowed by facilities such as CEBAF at Jefferson Lab, where the study of nuclei and the nucleon and its excitations by means of electron scattering can be carried out with unprecedented precision and completeness in a wide kinematic range. This volume should serve the graduate student and the researcher equally well.

Book Description
These proceedings contain selected topics covering various fields of collective motion and nuclear dynamics, ranging from low to high energies, from nuclear structure to reaction mechanisms, from regular stable to chaotic systems, and from fragmentation to fusion. Several ways of investigating the nuclear systems are presented: electron scattering radioactive beams, fragmenting projectiles, beta and double beta decays, and cluster emission. Their behaviour, under some extreme situations such as superdeformation, high spin states, high temperature, and relativisitic energy, is described within various theoretical formalisms.

Book Description
A series of new and relevant experimental results are here presented to the community for the first time. In particular, we refer to the measurement of the neutron spin structure functions by the SLAC (E142) and CERN (SMC) collaborations; the first results from MAMI on experiments with tagged photons (A1 collaboration), on electroproduction of multi-hadron final states (A2 collaboration) and the neutron form factor (A3 collaboration); the experiments on strangeness photoproduction at ELSA; the polarization experiments at Bates on the neutron form factor and nuclear response functions and the photon and electron scattering data obtained by the Genova-Frascati Jet Target collaboration.Focused on the study of spin observables and exclusive processes at high momenta, the following sessions were held: The Neutron Form Factors; Spin Structure Functions; Exclusive Processes at High υ and Q2. Deep Inelastic Scattering; Spin Observables; One- and Two-Nucleon Knockout at Low and Intermediate Energies; Excitation of Baryons Resonances and Strangeness.

Book Description
In recent years there has been growing interest in the nucleon-nucleon correl ations inside nuclei. In many respects the motions of the nucleons can be very well described by an overall mean field, so that the motion of each nucleon is governed by the mean field due to all the other nucleons. This concept underlies the Fermi-gas, Hartree-Fock and shell models and has enabled a range of nuclear properties to be calculated, often to surprising accuracy. It gradually became clear, however, that these mean-field models are limited by the effects due to the very strong interactions between the nucleons that occur at short distances; these are the short-range correlations. They are responsible for instance for the high-momentum components in the nucleon momentum dis tribution, and prevent the simultaneous description of the nuclear density and momentum distributions by the same mean field. It thus becomes necessary to develop methods for including the effects of nucleon correlations in nuclei, and these are the main subject of this book. Some related problems of nuclear structure were discussed in an earlier book by the same authors: Nucleon Momentum and Density Distributions in Nuclei (Clarendon Press, Oxford, 1988). The main aim of that book was to study the effects of nucleon-nucleon correlations, both short-range and tensor, on the nucleon momentum distribution, which is particularly sensitive to these correl ations, and on the nucleon density distribution.
