Abstract:
Here we report calculation of the differential interference angles (including b≤ ρ and b≥ρ ) for singlet-triplet mixed states of Na2(A1∑+u,v=8~b3Π0u,v=14) system in collision with Na, in order to study the collision induced quantum interference on rotational energy transfer in an atom-diatom system. The calculation is based on the first-order Born approximation of time-dependent perturbation theory, and the anisotropic Lennard-Jones interaction potentials are also employed. The relationships between differential interference angle and impact parameter, including collision diameter and velocity, are obtained.
Key words:  Rotational energy transfer, Collision-induced quantum interference, Interference angle

摘要:
对原子-双原子体系碰撞诱导转动传能进行了进一步的理论研 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,计算了 单-叁重混合态的Na2(A1∑+u,v=8~b3Π0u,v=14)体系与Na碰撞 的微分干涉角(b·?和b??),得到了微分干涉角与碰撞参数的关系,对 其碰撞量子干涉作出了定量准确的描述.
