Abstract
Phys.Rev.C66:044301,2002 Ground state properties of finite nuclei ($^{16}$O and $^{40}$Ca) are
evaluated from realistic nucleon-nucleon interactions. The calculations are
based on the Brueckner-Hartree-Fock approximation. Special attention is paid to
the role of the energy spectrum for the particle states, in particular for
those close to the Fermi energy. Additional binding energy is obtained from the
inclusion of the hole-hole scattering term within the framework of the Green
function approach. Results for the energy distribution of the single-particle
strength and the sensitivity to the nucleon-nucleon interaction are
investigated. For that purpose three modern nucleon-nucleon interactions are
employed: the Argonne V18, the charge dependent Bonn potential and a realistic
nucleon-nucleon interaction which is based on chiral perturbation theory and
which has recently been fitted by the Idaho group.
