DISTORTED WAVE-WAVE PACKET APPROACH TO VIBRATIONAL DEACTIVATION OF DIATOMIC MOLECULE BY COLLISIONS WITH SOLID SURFACE

A model is proposed for vibrational dexcitation of diatomic molecule by collisions with a solid surface, and used to predict the rotational and translational energy distributions and other properties of interest. It is found that molecular rotation dominates over translation in receiving the vibrational energy released, even for the heavier diatomic molecules.
