英文摘要: Collisional quantum interference on rotational energy transfer was observed by Sha et al. (J. Chem. Phys., 1995, 102, 2772) and the interference phase angle which determines the magnitudes of the transition cross sections was introduced there. Collisional quantum interference was also observed in Na-2 (A (1)Sigma(u)(+), v = 8 similar to b (3)Pi(ou), v = 14) system in collision with Na (Chem. Phys. Lett., 2000, 318, 107), but the interference angle had not been measured out due to the lack of enough experimental data. In this paper, we have computed the interference angles for singlet triplet mixed states of Na-2 (A (1)Sigma(u)(+), v = 8 similar to b(3) Pi(ou), v = 14) system in collision with Na by using the first order Born approximation of time dependent perturbation theory. Two different interaction potentials (long range attractive and Lennard-Jones interactions) have been employed to simulate the interference angles. The relationships of the interference angle versus temperature have been obtained. And the various factors that influence the interference angle have been discussed.
