THEORETICAL NUCLEAR PHYSICS.

Abstract

Abstract : A discussion of the unitary-model-operator approach to the correlation problem in nuclei is presented and some calculational details are discussed. Results are reported for Hartree-Fock calculations carried out with an effective interaction derived from the Yale potential. The spherical nuclei O16 and Ca40 are considered. The orbitals are expanded in terms of harmonic-oscillator functions, and the dependence of the results on the number of oscillator functions used and upon the oscillator size parameter is studied. Work during this period was carried on along the following lines: (a) Nucleon-nucleon scattering; (b) effective interactions between nucleons in finite nuclei; (c) nucleon-nucleon elastic scattering; (d) phase-shift analysis of elastic pion-nucleon scattering; (e) photodisintegration of the deuteron; (f) heavy ion scattering and transfer reactions, and (g) coulomb excitation.
