Shape of the Island of Superheavy Nuclei

Abstract
On the basis of the Strutinsky shell-correction method applied to realistic diffuse-surface potentials we have calculated the shape of the island of superheavy nuclei. With respect to spontaneous fission, the island is a mountain ridge extending from 114 protons to about 124 protons. The descent from the mountain down to the sea of instability is rather gentle for decreasing neutron numbers below 184, but is more rapid on the other three sides.
