摘要
在前期工作的基础上，对非对称几何条件下波函数中的索末菲参量作了进一步的完善。研究了索末菲参量对三重微分截面（ＴＤＣＳ）产生的影响。用新的索末菲参量计算了低能电子入射离化氢原子的ＴＤＣＳ。
Based on our earlier paper, the sommerfeld parameters in th BBK wave function are further modified in asymmetric geometry. The influence of the Sommerfeld parameters on the triple differential cross sections is considered. The triple differential cross sections for electron impact ionization of atomic hydrogen at low incident energies in asymmetric geometry are calculated by use of the modified sommerfeld parameters. The results were compared with those of the earlier paper and the theoretical results of the convergent colse-coupling method .It was found that the present results give a better description for the experimental data.
