THEORETICAL CALCULATION OF THE RELATIVISTIC SUBCONFIGURATION-AVERAGED TRANSITION ENERGIES

A method for calculating the average energies of relativistic subconfigurations in highly ionized heavy atoms has been developed in the framework of the multiconfigurational Dirac－Fock theory. The method is then used to calculate the average transition energies of the spin-orbit-split 3d－4p transition of Co-like tungsten, the 3d－5f transition of Cu-like tantalum, and the 3d－5f transitions of Cu-like and Zn-like gold samples. The calculated results are in good agreement with those calculated with the relativistic parametric potential method and also with the experimental results.
