ABSTRACT
Effective nucleus charges Z are calculated for electrons of 2 s- and 2 p-shells in atoms of heavy elements with the use of the Dirac-Sommerfeld relativistic formula. It is established that starting from Z = 87, a change of ∆ Z > 1 is observed when going to the subsequent element (∆ Z = 1), that is, anti-screening of a certain type takes place.
