Density distributions of superheavy nuclei

Abstract

We employed the Skyrme-Hartree-Fock model to investigate the density distributions and their dependence on nuclear shapes and isospins in the superheavy mass region. Different Skyrme forces were used for the calculations with a special comparison to the experimental data in 208Pb. The ground-state deformations, nuclear radii, neutron-skin thicknesses and α-decay energies were also calculated. Density distributions were discussed with the calculations of single-particle wave functions and shell fillings. Calculations show that deformations have considerable effects on the density distributions, with a detailed discussion on the 292120 nucleus. Earlier predictions of remarkably low central density are not supported when deformation is allowed for. © 2005 The American Physical Society.
