Abstract
Here we report calculation of the differential interference angles (including b and b) for singlet-triplet mixed states of Na2(A1u+, v=8 b30u, v=14)-Na system in collision with Na, in order to study the collision-induced quantum interference on rotational energy transfer in an atom-diatom system. The calculation is based on the first-order Born approximation of time-dependent perturbation theory, and the anisotropic Lennard-Jones interaction potentials are also employed. The relationships between differential interference angle and impact parameter, including collision diameter and velocity, are obtained.
