| Abstract: | The semi-classical theory approach to the inelastic collisions of atom-complieated molecule system has been studied. With geometric method we have derived expressions of the Hamilton of Ar--CH_4 in terms of action-angle variables,and the Monte-Carlo procedure is used to calculate the classi-cal trajectory integrals and corresponding S matrix elements. Our results are compared with the quantum conclusions. It is shown convincingly that this dynamical theory is valid. |
