The dispersion coefficients obtained are in fairly goodagreement with those acquired by the universally accepted method of Meyer et al. and theyalso conform with the outcome that K. T. Tang and J.

Using such a potential function, the author hascomputed the forty-four different kinds of vibrational and rotational excitation cross sectionsfor He-H<sub>2</sub> collision, and conducted research on the changing patterns of the partial wavecross sections for elastic atom-molecule collision and the partial wave excitation cross sectionsfor inelastic collision with the increase of quantum number.展开更多
