The general expression for rotational excitation and scattering cross sections for rigid diatomic molecules derived in Paper VIII is reduced to yield a restricted distorted‐wave approximation, resulting in a relatively simple equation for the inelastic transition probabilities. The new expressions possess significant advantage over analogous ones of Davison and of Arthurs and Dalgarno due to the elimination of certain multiple summations. The results are, however, demonstrated to be identical… CONTINUE READING
