QUANTUM-MECHANICAL CALCULATIONS OF COLLISION-INDUCED DISSOCIATION FORATOM-DIATOM REACTIVE SYSTEMS - ON THE SCATTERING BOUNDARY-CONDITION

An approximate method of Sakimoto and Onda for deriving the S-matrix e lements for dissociative collisions in collinear atom-diatom reactive systems, which provided accurate total dissociation probabilities, has been tested further. To do this, kinetic energy distributions of atom ic products have been calculated and compared with results given by Ka ye and Kuppermann. The method of Sakimoto and Onda always gives an art ificial dip structure in the kinetic energy distributions. Further stu dies are required to resolve the double continuum problem in dissociat ive collisions.
