A program for ion-atom collisions involving one electron

Abstract
A program to compute transition amplitudes in the rectilinear-path impact-parameter formulation, for collision processes in which one of the colliding systems is a hydrogen atom or a hydrogenic ion and the other is a bare nucleus, is described. The time-dependent wave function is expressed in orthogonal polynomials in coordinates that, for any given value of the time, are linear functions of the distances of the electron from the two nuclei. Two different methods are used for obtaining approx...

摘要
本文描述了一款用于直线路径碰撞参数近似下跃迁振幅计算的程序，适用于碰撞体系其中一方为氢原子或类氢离子（hydrogenic ion）、另一方为裸核（bare nucleus）的碰撞过程。该程序将含时波函数（time-dependent wave function）表示为坐标下的正交多项式（orthogonal polynomials），在任意给定时刻，这些坐标均为电子到两个原子核距离的线性函数。本文采用两种不同方法以获取近似……
