The interaction potentials for He-He and He-Li+

Abstract
The He-He and He-Li+ potentials are investigated by means of extensive STO SCF and configuration interaction calculations. The calculated molecular constants r m and εm are 5·61 a.u. and 9·81 K for He-He which are very close to experiment. The calculated potential curve for He-Li+ is also considered to be reliable; r m=3·63 a.u. and εm=0·072 eV.
