不同能量下He原子与HCl分子碰撞激发分波截面的同位素效应研究

Isotope effect of He-HCl collisions on the partial wave cross sections in different energies

基于Huxley势函数的拟合势,通过精确度较高的密耦近似方法计算了入射能量为50 meV和150meV时,氦原子的四种同位素~3He,~4He,~9He,^(10)He与HC1分子碰撞体系的激发分波截面.通过分析不同能量下,各碰撞体系分波截面的差异,探讨了不同入射能量时He的同位素对He-HCl碰撞体系的分波截面的影响,总结出其分波截面随量子数和体系约化质量的变化规律.

It is based on the fit potential of Huxley analytic function that the partial wave cross sections of 3He, 4He, 9He, 10He with HCl systems are calculated by the accurate close-coupling method when the incident energies are 50meV and 150meV. By analyzing the partial wave cross sections in different energies and the isotopic effect, the changing tendencies of the partial wave cross sections with the quantum number and reduced mass in the isotopic substitution systems are obtained.
