Probability of excitation of vibrations and dissociation of diatomic molecules

A numerical solution is given for the dynamic problem of collision between an atom and a diatomic molecule for the case of O₂ and Ar within the framework of classical mechanics. The molecule is approximated by the Rydberg-Klein-Riess oscillator. The probabilities of change in the vibrational state and dissociation of the molecule are calculated by the method of varying the initial conditions.The authors are indebted to N. A. Generalov, V. B. Leonas, and A. I. Osipov for useful discussion.
