Ground state of superheavy elements with $120\le Z\le 170$: systematic study of the electron-correlation, Breit, and QED effects

Abstract

For superheavy elements with atomic numbers $120\le Z\le 170$, the concept of the ground-state configuration is being reexamined. To this end, relativistic calculations of the electronic structure of the low-lying levels are carried out by means of the Dirac-Fock and configuration-interaction methods.The magnetic and retardation parts of the Breit interaction as well as the QED effects are taken into account. The influence of the relativistic, QED, and electron-electron correlation effects on the determination of the ground-state is analyzed.
