Influences of the low collision energies and isotopic variants on the stereodynamics for reactions Li+DF/TF→LiF+D/T

Abstract

Stereodynamics for Li+DF/TF→LiF+D/T reactions are studied using the quasi-classical trajectory method based on a new potential energy surface constructed by Aguado and Paniaga [J. Chem. Phys. 119 (2003) 10088]. The product angular distributions of and , which reflect the vector correlation, are calculated and discussed. The average rotational alignment factor 〈 〉 as function of the collision energy is also presented. Furthermore, four polarization-dependent differential cross sections (PDDCSs), namely, PDDCS00, PDDCS20, PDDCS21and PDDCS22+ are calculated as well. By comparing the stereodynamics results of the title reactions, we find that the isotopic effects are relatively obvious.
