A Theoretical Study on the Partial Wave Cross Section of Collisionsfor Low Energy Inertia Atoms and H2(D2,T2)
【摘要】 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.
【Abstract】 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.
