Abstract

The effects of correlations on the bulk properties of nuclei are investigated in large model spaces including up to 21 single-particle orbits. The evaluation of the single-particle Green function is made feasible by means of the BAGEL approximation. The spectral function for single-nucleon pick-up and removal is investigated for the nuclei ¹⁶O and ⁴⁰Ca . Special attention is paid to the effects produced by correlations on the calculated ground state properties of closed shell nuclei. It is observed that correlations beyond the Brueckner Hartree Fock approximation tend to improve the results obtained using realistic nucleon nucleon interactions.
