Based on the experimental data of crossed collisions of He and Ne atomic beams, the He-Ne interatomic potential has been derived by the inversion scattering theory. The obtained potential exhihits proper characters of weak van der Waals potential, that is, strong repulsive in the short range, weak atrractive similar to bowl in the intermediate range and vanish in the long range. This potential can produce correct results in good agreement with experimental data.
