Abstract :
A semiclassical method, which treats the vibrational motion quantum mechanically and the relative motion classically, is applied to study collision induced dissociation in He + H2. The semiclassical method provides a reasonable agreement with previous full quantum mechanical results [K. Nobusada, K. Sakimoto, Chem. Phys. 197 (1995) 147], and is very useful to gain a deep understanding of the dissociation dynamics. The method also enables us to discuss some quantum mechanical effects found in the full quantum mechanical study.
