-related Quantum Interference of 2 [Case(a)] Diatom on Rotational Energy Transfer

Abstract

To study theoretically the relationship between the integral interference angle and the scattering angle in collisional quantum interference, the integral interference angle of atom-2[case(a)] diatomic molecules system is described. To simulate the experiment theoretically, the theoretical model on collision-induced rotational energy transfer in an atom-2[case(a)]diatom system is presented based on the first order Born approximation taking into account of the long-range interaction potential. For the 2 electronic state in the Hund's case(a) diatom, the degree of the interference is discussed. The interference angles of collision-induced rotational energy transfer of CN(A2) in Hund's case(a) with He, Ne, and Ar are calculated quantitatively. The key parameters in the determination of integral interference angles are obtained.
