CO-He碰撞系统态-态传能截面的研究

State-to-state rotation cross-sections of collision system

通过波恩近似理论对双原子激发态转动传能中量子干涉效应相关信息进行深入研究,利用各向异性相互作用势建立了传能截面的理论模型,得到了转动传能因碰撞能量的不同而产生的差异,传能截面随着初末量子数、散射角的变化关系.讨论了散射角和碰撞能量对传能截面的影响.

Collisonal quantum interference （CQI）in the intramolecular rotational energy transfer was re-searched basing on Born approximation.The theoretical model of cross-section is constructed with aniso-tropic Lennard-Jones interaction potentials,the conclusions that collisional energy passing channels are different with different collision energy,cross-section have relation of the final quantum state and scat-tering angle are desired.The relations cross-section with scattering angle and collision energy are dis-cussed.
