U. Kleinekathofer, Ground state potentials for alkaline-earth-helium diatoms calculated by the surface integral method, CHEM P LETT, 324(5-6), 2000, pp. 403-410
Using a recently derived simple formula the van der Waals ground state pote
ntial curves of alkaline-earth-helium pairs BeHe, MgHe, CaHe, SrHe, and BaH
e have been calculated. The repulsive potential is based on exchange energi
es calculated from the surface integral method applied to multielectron sys
tems. With the exception of the long-range dispersion coefficients all the
input parameters are atomic properties of the free atoms. The agreement wit
h the available potentials from the literature is reasonable. (C) 2000 Else
