Abstract

A systematic search for the location of islands of stability has been performed for the proton number100 Z 220 and the neutron numberZ+ 30 N 2Z+ 30 using covariant density functional theory (CDFT),a relativistic Hartree{Bogoliubov (RHB) formalism with separable pairing, for two different force parameters, DD-ME2and NL3*. Locations of the islands of stability are identi ed by analysis of the two-neutron and two-proton separationenergy, two-nucleon shell gaps, vanishing neutron and proton pairing gap, energy surface, and the single particle states.The results show that beyond292120 only Z = 154 and N>220 can be a center of a new island of stability.
