    "abstract": "We describe the properties of the neutron rich nuclei around N=28 in the\nshell mode framework. The valence space comprises the $sd$ shell for protons an\nthe $pf$ shell for neutrons without any restriction. Good agreement is found\nwith the available experimental data. The N=28 shell closure, even if eroded\ndue to the large neutron excess, persists. The calculations predict that\n$^{40}$S and $^{42}$S are deformed with $\\beta=0.29 $ and $\\beta=0.32$\nrespectively.",
