Single particle spectra based of modern effective interactions

Abstract

The self-consistent Green's function method is applied to 16O using a G-matrix and Vucom as effective interactions, both derived from the Argonne v18 potential. The present calculations are performed in a larger model space than previously possible. The experimental single particle spectra obtained with the G-matrix are essentially independent of the oscillator length of the basis. The results shows that Vucom better reproduces spin-orbit splittings but tends to overestimate the gap at the Fermi energy.
