Differential Interference Angle of Collision-induced Rotational Energy Transfer in Na2(A1∑+u , v=8~ b3Π0u, v=14)-Na System

Here we report calculation of the differential interference angles (including b≤ ρ and b≥ρ ) for singlet-triplet mixed states of Na2(A1∑+u，v=8~b3Π0u，v=14) 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.
