Title: New effective interaction for 0({Dirac_h}/2{pi}){omega} shell-model calculations in the sd-pf valence space

Abstract

The neutron-rich isotopes with Z{<=}20, in particular those with neutron numbers around N=28, have been the focus of a lot experimental and theoretical scrutiny during the past few years. Shell-model calculations using the effective interaction SDPF-NR were able to predict or to explain most of the properties featured by these nuclei. Prominent among them is the disappearance of the N=28 shell closure for Z{<=}16. We have incorporated into SDPF-NR some modifications, either on purely theoretical grounds or guided by new experimental information. The proposed interaction SDPF-U offers enhanced reliability with respect to the earlier version.
