Theoretical and Experimental Studies of Molecular Dynamics
Abstract
We report a study of very low energy collision induced vibrational relaxation using an approximate resonant state formalism which relates the inelastic cross section to the properties of metastable states. A study of models reveals that the combined effect of low collision energy resonance and high initial diatomic vibrational excitation can lead to a large enhancement of the vibrational relaxation cross section. In general, both the Wigner threshold requirement, is the initial relative momentum, and the existence of collision energy resonances can lead to increases in the very low energy relaxation cross section. Indeed, the threshold requirement increasingly enhances the contribution of a resonance to the cross section the closer the resonance is to zero collision energy. (jes)
