Classical model for laser-induced nonadiabatic collision processes
By synthesizing earlier work of Orel and Miller and of Meyer, McCurdy, and Miller, a model for describing laser-induced electronically nonadiabatic collision processes is constructed which treats all degrees of freedom: heavy particle (i.e., translation, rotation, and vibration) electronic, and photon: by classical mechanics. This then makes it relatively easy to carry out calculations to simulate such processes within a dynamically consistent framework. Application is made to the test case H+LiF..-->..Li+HF reaction considered by Light and Altenberger-Siczek. The most interesting feature revealed by these classical calculations is maxima in the reaction probability as a function of initial translational energy at energies below the laser-free threshold. It is seen that this structure can be understood as a Franck--Condon-like effect.
