• rotational energy transfer
• collision-induced quantum interference
• interference angle

Here we report calculation of the differential interference angles (including b <= rho and b >= rho) for singlet-triplet mixed states of Na-2(A(1)Sigma(+)(u), upsilon=8 similar to b(3)Pi(0u), upsilon=14) system in collision with Na, in order to study the collision-induced quantum interference on rotational energy transfer in ail 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.
