Description
We have carried out calculations to investigate Van der Waals two-body dispersion coefficients C8, C10 and C12 for the H(1s 2S)-He(1s21S) system with screened Coulomb interactions in the framework of a powerful computational technique. The dispersion coefficients for different screening parameters ranging from 0 to 1a-10 are reported. In the unscreened case, the C12 coefficient is reported for the first time in the literature.
