✦ Synopsis
The van der Waals potential curves of H2(35~), He 2, Ne 2, HeNe, HHe, Lille, NaHe, KHe, RbHe and CsHe have been calculated using a recently derived simple analytical formula. The repulsive potential is based on exchange energies calculated from the surface integral method applied to multielectron systems. With the exception of the long-range dispersion coefficients, all the input parameters are atomic properties of the free constituent atoms. The calculated curves agree well with both experimental and ab initio theoretical data.
