摘要: 解决了包含四个合流超几何函数的数值积分问题,从而给出了计算电子碰撞电离离子三重微分截面的通用方法,适合于中、高入射能量下的各种几何条件。计算了对称和不对称几何条件下电子碰撞电离He+离子的三重微分截面,并与其它理论结果作了比较。

Abstract: For calculating integrals involving four confluent hypergeometric functions, a general theoretical method is presented, which is valid for both symmetric and asymmetric geometries to determine the triple differential cross sections (TDCS) for electron impact ionization of ions. The TDCS for the ionization of hydrogenic ion at high and intermediate energies have also been calculated and compared with the existing theoretical results.

Key words: electron impact ionization, ion, triple differential cross sections
