Abstract:
As a further theoretical study of the collision-induced quantum interference on rotational energy transfer in an atom-diatom system, based on the first-Born approximation of time-dependent perturbation theory, taking into account the anisotropic Lennard-Jones interaction potential and the long-range interaction potential, the differential interference angles in singlet-triplet mixed states of CO A1Ⅱ(v=0)~e3∑-(v=1)system in collision with He, Ne, Ar, and other partners were calculated theoretically. The relationships of differential interference angle versus impact parameters, including collision parameter b and velocity, are obtained.

摘要:
通过对原子-双原子体系碰撞诱导转动传能的理论研究,在含时一级波恩近似的基础上考虑各向异性相互作用势和长程相互作用势,计算了单叁混合态的CO A1Ⅱ(v=0)~e3∑-(v=1)和He、Ne、Ar碰撞的微分干涉角,并得到了微分干涉角与碰撞参数的关系.
