THE SUDDEN APPROXIMATION APPLIED TO ROTATIONAL EXCITATION OF MOLECULES BY ATOMS. I. LOW ANGLE SCATTERING,
Abstract
The sudden approximation is applied to the calcu lation of transition probabilities and cross sections for rotational excitation and scattering of homonuclear diatomic molecules by atoms. The present analysis is restricted to a consideration of the influence of the anisotropy and strength of the long-range attractive part of the inter action potential only; its applicability is thus limited to the low angle scattering problem. Nevertheless, the results illustrate the main features of the method applied to inelastic molecular collisions in general, and demonstrate its advantage over the first-order perturbation approximation. Low angle differential inelastic scattering cross sections would yield directly the anisotropy of the long-range attractive potential. (Author)
