Abstract
We describe the properties of the neutron-rich nuclei around N=28 in t he shell mode framework. The valence space includes the sd shell for p rotons and the pf shell for neutrons without any restriction. Good agr eement is found with the available experimental data. The N=28 shell c losure persists, even if eroded by the large neutron excess. The calcu lations predict that S-40 and S-42 are deformed with beta=0.29 and bet a=0.32 respectively.
