NO Case(b)情况下的非弹性散射及Λ相关量子干涉的理解（英文）

The inelastic scattering of NO [Case(b)] and an understanding of the Λ-related quantum interference

在理论研究中,对洪德情况(a)下2Π态原子-双原子分子碰撞诱导转动传能中的量子干涉已经进行了研究.为了对Λ相关的原子-双原子分子碰撞系统进行更进一步的研究,建立了洪德情况(b)下原子-双原子分子动力学模型.讨论洪德情况(b)下双原子分子的干涉程度,对NO洪德情况(b)下与He、Ne、Ar碰撞的干涉角进行了定量计算.在含时一级波恩近似下,考虑各向异性相互作用势,讨论各个因素(实验温度、碰撞伴、转动量子数等)对干涉角的影响.

In our theoretical studies,the quantum interference on collision-induced rotational energy transfer of atom-2Π[case（a） ]diatomic with inert gases was reported. As a further theoretical study of the collision-induced Λ-related quantum interference on rotational energy transfer in an atom-diatom system,a dynamic model of atom-2Π[case（b） ] diatomic molecules system is described in this paper. For the2Πelectronic state in the Hund＇s case（b） diatomic,degree of the interference is discussed. The interference angles of collision-induced rotational energy transfer of NO（X2Π） in Hund＇s case（b） with He,Ne and Ar are calculated quantitatively. Based on the time dependent first order Born approximation,and taking into accounts the anisotropic Lennard-Jones interaction potentials,the effects of several factors（rotational quantum number experimental temperature and partner） that the interference angle depends on are investigated.
