摘要：
We have carried out calculations to investigate Van der Waals two-body dispersion coefficients C(8), C(10) and C(12) for the H(1s (2)S)-He(1s(2 1)S) 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(0)(-1) are reported. In the unscreened case, the C(12) coefficient is reported for the first time in the literature.
