Quantum infomation from classical trajectories: Scaling deconvolution of moments in diatom-diatom collisions

Abstract

An inversion procedure to obtain quantal transition probabilities from the analysis of classical moments has been applied to various model diatom-diatom collision systems. This inversion relies on the use of a scaling theory to analyse classical moments and the subsequent use of a quantal scaling theory in interpretation of the classical scaling coefficients. We obtain transition probabilities that are in good agreement with exact quantum studies, and also compare favorably with other moment inversion schemes that have been described earlier in the literature.
