摘要: Abstract Using a recently derived simple formula the van der Waals ground state potential curves of alkaline-earth–helium pairs BeHe, MgHe, CaHe, SrHe, and BaHe have been calculated. The repulsive is based on exchange energies calculated from surface integral method applied to multielectron systems. With exception long-range dispersion coefficients all input parameters are atomic properties free atoms. agreement with available potentials literature reasonable.
