He同位素与HCl碰撞分波截面的理论计算

The calculation of the partial wave cross sections for the collisions of He isotope with HCl

采用Huxley势函数拟合得到He-HCl较为可靠的相互作用势,使用精确度较高的密耦近似方法计算了入射能量为80meV时,氦原子的三种同位素3He,4He,10He与HCl分子碰撞体系的激发分波截面。通过分析各碰撞体系分波截面的差异,探讨了He(3He、4He、10He)-HCl碰撞体系的弹性分波截面00-00,非弹性碰撞转动激发分波截面00-01到00-07,随量子数和体系约化质量的变化规律。

In this paper, more accurate datas of potential energy surface can be gained by using Hux- ley function fitting, the Close-coupling method are applied to the collisions of 3He, 4He, 10He with HCI systems when incident energy is 80meV. The partial wave cross sections are calculated. By analy- zing the elastic partial wave cross sections 00 -00 and the inelastic collision rotational excitation partial wave cross sections 00 -01 to 00 -07, the changing tendencies of the partial wave cross sections with the quantum number and reduced mass in the isotopic substitution systems are obtained.
