Abstract
A detailed calculation based on the strong-coupling correspondence principle has been made of rotational transitions in collisions between rare-gas atoms and electronically excited Li2 to compare with recent measurements. Most of the cross sections can be reproduced within the experimental accuracy using a simple Lennard-Jones potential with large repulsive and attractive anisotropies. Many of these collisions are sudden for which case it is shown that ratio of cross sections for upward and downward transitions from the same level is determined primarily by detailed-balance requirements and yields little information on the potential surface.Keywords
