A general program to calculate atomic continuum processes using the R-matrix method

Title of program: RMATRX STG3 Catalogue Id: AAHC_v1_0 Nature of problem This program reads the hamiltonian matrix elements etc. stored on a permanent tape or disc file by RMATRX STG2. It then diagonalizes this matrix and calculates the R-matrix and the Buttle correction. Then either the electron atom or ion cross-section, the photoionization cross-section or the frequency dependent polarizability for a range of incident energies or frequencies is calculated.

程序名称：RMATRX STG3 目录编号：AAHC_v1_0 问题概述。本程序可读取由RMATRX STG2存储于永久磁带或磁盘文件中的哈密顿量（Hamiltonian）矩阵元等相关数据，随后对该矩阵进行对角化运算，并计算R矩阵（R-matrix）与巴特勒校正（Buttle correction）。接着可针对一系列入射能量或频率，计算电子-原子/离子碰撞截面、光电离截面或频率依赖性极化率中的任意一类。本程序的版本收录于Mendeley数据平台的CPC程序库中，相关条目信息为：AAHC_v1_0；RMATRX STG3；10.1016/0010-4655(74)90096-4。本程序源自贝尔法斯特女王大学维护的CPC程序库（1969-2019）。
