Study of Collisions Between H_2(D_2,T_2) and He(E=0.1 eV)

对H2 ,D2 ,T2 碰撞体系 ,采用Tang Toennies势 ,用密耦方法求解散射方程 ,计算了 E =0 .1eV 时 0 0 0 0 ,0 0 0 2 ,0 0 0 4分子转动激发分波截面和角分布 ,并研究了原子与分子碰撞弹性分波截面和非弹性激发截面随量子数增加的变化规律。

In this paper,Tang Toennies potential is applied to the He H 2(D 2,T 2) system,using close coupling equation,molecular rotational excitation cross esctions and angular distrbutions of 00 00,00 02 and 00 04 excitation have been calculated,and conducted research on the changing patterns of the partial wave cross sections for elastic atom molecule collision and the partial wave excitation cross sections for inelastic collision with the increase of quantum number.
