Description

In the present report, localization properties of valence electronic density are studied for superheavy atoms in the range 112 ≤ Z ≤ 120. Atomic shell structure is revealed by means of electronic localization function in the Dirac-Fock approximation (ELF) [1]. Predictions for the radii and widths of the valence shells based on the ELF are compared with the radii and widths of the related Dirac-Fock orbitals. The data obtained for superheavy atoms with 112 ≤ Z ≤ 120 are compared with the corresponding results for atoms with 30 ≤ Z ≤ 38 and 80 ≤ Z ≤ 88. The influence of the relativistic effects on the distribution of the valence electronic density is estimated by performing the related calculations in the non-relativistic limit.
