Further theoretical study of collisional quantum interference on rotational energy transfer in an atom diatom system

In our previous study (M.-T. Sun, G.-H. Sha, S.-L. Cong, F.-C. Ma, J.-C. Xie and C.-H. Zhang, Chem. Phys. Lett., 2001, 339, 413), a method of calculating the interference angle theoretically was presented, and experiments on the system CO A(1)Pi(v = 0) similar to e(3) Sigma(-)(v = 1) in collision with He were simulated. As a further theoretical study of the collision-induced quantum interference on rotational energy transfer in an atom diatom system, a dynamic model is described in this paper, based on the first order Born approximation of the time dependent perturbation theory and taking into account the anisotropic Lennard-Jones interaction potential. Experiments on the system CO A(1)Pi(v = 0) similar to e(3) Sigma(-) (v = 1) in collision with Ne and Ar in a sample cell are simulated. The integral interference phase angles are computed under both homonuclear and non-homonuclear approximations. The results are perfectly satisfactory under the latter condition.
