The Slater transition-state method for binding energies in the relativistic local density R Xi method

Neutral-atom binding energies, computed using the Slater transition-state concept in the relativistic Xi method, are reported for various atoms. It is shown that the relaxation and relativistic effects are well accounted for by the present relativistic transition-state calculations. The reported values are generally in good agreement with the experimental values and the agreement is particularly satisfactory in the case of valence levels. Slight discrepancies in the 1s level of heavier atoms may be due to the Breit interaction corrections and because finite-nuclear-size effects are not accounted for fully in the present calculations
