  • 基于发展的分子间相互作用势, 采用密耦方法计算了入射能量从1到140?meV范围内He原子与HI分子碰撞的微分截面、分波截面和积分截面.通过与He-HX(X=F,Cl,Br)体系分波截面的比较, 印证了He-HI体系相互作用势以及密耦计算结果的可靠性.结果表明:小角散射的概率大于大角散射的概率;碰撞能量越高,散射概率就越小, 尾部效应也越弱.总积分截面主要来自弹性碰撞的贡献;非弹性积分截面以00→01和00→02跃迁的贡献为主,其中00→02跃迁的贡献最大.
    The intermolecular interaction potential developed in our previous research and close-coupling method are applied to the HI-He system, and the differential cross sections, partial cross sections (PCSs) and integral cross sections (ICSs) at the incident energies from 1 to 140?meV are calculated. The reliability of the interaction potential for He-HI system and the close-coupling calculations have been verified by comparing with the PCSs of He-HX (X=F, Cl, Br) systems. The results show: (1) The probability at small scattering angles is larger than that for large scattering angles. With the increase of collision energy, the scattering probability and the tail effect fall down. (2) Total ICSs mainly come from the elastic collisions. The transitions of 00 → 01and 02 contribute to the total inelastic ICSs predominantly.
