Abstract

Generalizations of the number conserving sets for the effective charge were examined and no significant enhancements in the total contributions were found. The SCCE approach of Kirson was modified so as to remove c.m. effects approximately and to include particle-particle interactions using a doubly partitioned G-matrix. Both effects were found to enhance the core polarization. The oscillator basis was replaced by a simulated HF basis, which reduced the core polarization so that it became too small in comparison with experiment.

      The Green’s function Monte Carlo calculations of the Argonne–Urbana group [10–12] and the recent no-core shell-model calculations [74, 138] clearly indicate the need for three-body forces. Similar arguments, based on an analysis of 0p, 1s0d and 1p0f nuclei by Zuker [139] lend support to this picture for heavier nuclei as well. Real three-body forces are necessary in order to reproduce the saturation properties of nuclear matter as well, see for example [46].
