量子干涉效应中干涉角和散射角的研究

The relation of differential interference and scattering angle in theory of collisional quantum interference

利用波恩近似理论对双原子激发态转动传能进行了剖析,更深入的研究了原子分子碰撞过程中量子干涉效应相关信息.利用各项异性相互作用势和直线轨迹近似建立了新的量子干涉模型,讨论了原子与双原子分子碰撞时散射角和微分干涉角的关系,得到了干涉角和各向异性参数及转动量子数的关系.

To observe more precise information of collisional quantum interference（CQI） on rotational energy transfer,the theoretical model of CQI is described in an atom-diatom system in the condition of the molecular beam by using the first-Born approximation of time dependent perturbation theory and taking into account the anisotropic Lennard-Jones interaction potentials.The changing tendencies of the differential interference angle with the scattering angle,rotational quantum numbers and collision partner are discussed.This theoretical model is important to understanding or performing this kind of experiments.
