A SEMICLASSICAL STUDY OF DISSOCIATION DYNAMICS IN HE-2 COLLISIONS(H)

A semiclassical method, which treats the vibrational motion quantum me chanically and the relative motion classically, is applied to study co llision induced dissociation in He + H-2. The semiclassical method pro vides a reasonable agreement with previous full quantum mechanical res ults [K. Nobusada, K. Sakimoto, Chem. Phys. 197 (1995) 147], and is ve ry useful to gain a deep understanding of the dissociation dynamics. T he method also enables us to discuss some quantum mechanical effects f ound in the full quantum mechanical study. (C) 1998 Elsevier Science B .V. All rights reserved.
