Abstract
The semiclassical strong-coupling correspondence principle of Percival and Richards (1970) has been used to obtain cross sections for simultaneous rotational and vibrational transitions in He+H2 collisions. The Gordon-Secrest potential surface has been used with a harmonic-oscillator representation of the molecular vibrational potential. Comparisons with close-coupling, coupled-states and effective-potential calculations show the strong-coupling correspondence principle to be surprisingly accurate even for transitions from low-lying levels.Keywords
