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.

摘要:
为了从理论上研究碰撞转动传能量子干涉中积分干涉角与散射角之间的关系,在洪德a情况下提出了原子-双原子分子体系积分干涉角.在一级波恩近似的基础上,考虑了长程相互作用势,提出了双原子分子Λ分裂2∏态洪德a情况下碰撞诱导转动传能的理论模型.在洪德a情况下讨论了干涉程度,并定量地计算了CN(A2∏)在洪德a情况下与碰撞伴He、Ne和Ar的碰撞诱导转动传能的干涉角,进而得到了与积分干涉角有关的各个参量.
