ONE-ELECTRON MODEL POTENTIAL CALCULATIONS OF VANDERWAALS FORCES .1. HE-STAR (21S, 23S) + NE, AR, KR, XE

A simple model which treats only the outer s electron on He* explicitly is shown to account for the main features and trends in the potential energy curves derived from scattering measurements on the title systems. The calculations demonstrate the importance of hybridization of the 2s orbital (2s–2pσ mixing) in determining the van der Waals forces, confirming earlier conclusions based on all-electron ab initio studies and experimental findings on He* (2 1S) systems. © 1979, American Institute of Physics.
