Shell-model data from a realistic N-N interaction: (III). Self-consistent starting energies

Abstract

It is shown that the inclusion of higher-order corrections in the Goldstone expansion together with a self-consistent treatment of the starting energy leads to improved values for the ground state binding energies in 16O and 40Ca. At the same time, excellent agreement is obtained between the calculated and experimental single-particle energies. Using these calculated single-particle energies and reaction matrix elements in a RPA calculation leads to an improved description of the negative-parity states in these nuclei.
