Electronic Configurations of Superheavy Elements

Abstract

We study electronic configurations of superheavy elementsaround one of islands of stabilities, from element 121 to 131,using the relativistic density functional theorywith quantum electrodynamical corrections (Breit interaction) by MacDonald and Vosko.It is found that these corrections are important for studying electronic configurations of superheavy elements,and that g electrons in the atom first appear from element 126.We draw a table for the electronic configuration of elementsincluding these superheavy elements.
