A Theoretical Study on the Partial Wave Cross Section of Collisionsfor Low Energy Inertia Atoms and H_2(D_2,T_2)

用密耦计算方法及Tang-Toennies势模型计算了E=0.05eV时,He、Ne、Ar、Kr、Xe与H2(D2、T2)碰撞体系的分波截面,从而得到了H2分子及其对称同位素替代情形下整簇惰性气体原子与H2(D2、T2)分子碰撞分波截面随量子数增加和体系约化质量的变化规律.

In this paper, the close-coupling equation and Tang-Toennies potential are applied to He, Ne, Ar, Kr, Xe-H2 （D2, T2 ） system, and the partial wave cross sections at collision energy E = 0.05 eV are calculated. In the presence of isotope substitution, the change rule of the partial wave cross sections of collision for low energy inertia atoms and H2 （D2, T2 ） with the increase of quantum number and the variations in the reduced mass of systems have been obtained.
