The Mutual Repulsive Potential of Closed Shells

Abstract

A method is developed for representing, in terms of a small number of integrals, the mutual potential of two ions or atoms having a rare gas electron configuration. The accuracy is the usual first approximation of the Heitler-London method. The integrals are evaluated for two like atoms, and numerical calculations made for two neon atoms. The total (repulsive) potential at R=1.8×10-8 cm is 344×10-14 erg; at R=2.3×10-8 cm, 35×10-14 erg; and at R=3.2×10-8 cm, 0.4×10-14 erg.
