ION2 — Calculation of single ionisation total cross section using the continuum distorted-wave eikonal initial-state approximation

Abstract Two programs are presented, namely ION2A and ION2B, which calculate the total cross section for the ionisation of hydrogen-like targets by fully stripped projectile ions from within the continuum distorted-wave final-state, eikonal initial-state (CDWEIS) approximation (D.S.F. Crothers and J.F. McCann, J. Phys. B 16 (1983) 3229). ION2A calculates the total cross section within the wave treatment and ION2B within the impact parameter (ϱ) treatment. The impact parameter code tests the validity o...

Crothers与J.F. McCann，《Journal of Physics B》第16卷(1983年)第3229页），用于计算完全剥离入射离子轰击类氢靶时的电离总截面。其中ION2A采用波函数方法计算总截面，ION2B则采用碰撞参数（ϱ）方法进行计算。该碰撞参数程序可验证…… **程序名称**：ION2A - ION2B **目录编号**：ADAT_v1_0 **程序用途** ION2A/B可计算多电荷完全剥离入射离子轰击类氢原子时的电离总截面与微分截面。 **Mendeley Data中CPC程序库收录的该程序版本** ADAT_v1_0；ION2A - ION2B；10.1016/0010-4655(94)00154-T 本程序源自贝尔法斯特女王大学馆藏的CPC程序库（1969-2019年）
