โœฆ Synopsis

Transition probabilities for the collision induced dissociation reaction.

A + BC -A + B + C. are calculnted for :I harmonic oscillator model using n semiclassical approximntion.

One of the unique features of this investigation is the nppearnnce of quantum oscillations

in the dissocintion probability as a function of collision cnerg?-. The number of oscillations is correlated to the number of bound states of the BC molecule.
