Shell Model Study of the Neutron-Rich Nuclei around N=28

Nuclear Theory 2008-11-26 v1

Abstract

We describe the properties of the neutron rich nuclei around N=28 in the shell mode framework. The valence space comprises the sdsd shell for protons an the pfpf shell for neutrons without any restriction. Good agreement is found with the available experimental data. The N=28 shell closure, even if eroded due to the large neutron excess, persists. The calculations predict that 40^{40}S and 42^{42}S are deformed with β=0.29\beta=0.29 and β=0.32\beta=0.32 respectively.
