Electron-electron interaction and antishielding constants of core shells of atoms

Abstract

Self-consistent Sternheimer antishielding constants for chemical elements with nuclear charge in the range 2-94 are obtained within the framework of the local density approximation. The dependence of the Sternheimer factors on the ion charge states is discussed. These results can be employed for a prediction of the quadrupole splitting parameters on the basis of pseudopotential electron density calculations.
