Abstract

Incorporating effective nucleon mass from the noncovariant energy-density functional, the Schr"odinger-equivalent central and spin-orbit mean-field potentials are determined and used in the microscopic-macroscopic method to calculate the ground-state shell corrections in superheavy nuclei with the charge numbers Z=112--126. The island of stability of superheavy nuclei is found to be rather flat and looks like one of coral reef origin due to the interplay between the proton shells at Z=114 and 120, and neutron shells at N=174 and 184, respectively. The shape coexistence in superheavy nuclei depends on spin-orbit potentials and can affect the spectrum of \ensuremathα decay. The one-quasiparticle spectra, isomeric states, and possible \ensuremathα-decay energies are predicted in the nuclei of \ensuremathα-decay chains of ²⁹⁵119 and ^295--297,299120.
