Nuclear theory group progress report and renewal proposal, December 1, 1980-November 30, 1981. [Dept. of Physics, SUNY at Stony Brook, proposal for 12/1/80-11/30/81]
This report covers a broad range of topics in theoretical nuclear physics, intermediate energy physics, and nuclear astrophysics. Primary emphasis is placed on understanding the nature of the nucleon-nucleon and meson-nucleon interactions and on related questions regarding the structure of baryons. A number of these questions are addressed with the aid of the chiral bag model. Starting from the free interaction, many-body techniques are used to construct the effective interaction between nucleons in nuclei and nuclear media and optical potentials for the description of the scattering of nucleons by nuclei. A wide range of nuclear phenomena are amenable to analysis using such effective interactions. Among the most interesting are nuclear giant resonances, for which are offered both new semiclassical insight and a new dynamical theory of nuclear vibrations that emphasizes the importance of the energy dependence of the effective interaction. The extension of Jastrow/hypernetted chain techniques and a better understanding of their content has led to a better description of the ground-state correlations in nuclear matter and a variety of other condensed systems. The equation of state of nuclear matter at densities of astrophysical interest is discussed. It is possible to understand the properties of pulsars given the interactions between their constituents. A description of pulsar formation and of the effects of the shock wave generated in the collapse of large stars is given. Heavy-ion reactions, quasimolecular states, and energy dissipation are studied through the excitation of collective excitations within a semiclassical framework. Items in this report are of the nature of extended abstracts. References to complete papers are given.
