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

Title of program: RMATRX STG1 Catalogue Id: AAHA_v1_0 Nature of problem This program calculates all one-electron, two electron and multipole radial integrals involving the bound and continuum orbitals necessary to enable electron atom or ion scattering, photoionization or frequency dependent polarizabilities to be calculated for a general atomic system. The bound orbitals are specified analytically. The continuum orbitals are calculated by the program. The integrals are stored on a permanent tape or disc file for use by RMATRX STG2. Versions of this program held in the CPC repository in Mendeley Data AAHA_v1_0; RMATRX STG1; 10.1016/0010-4655(74)90096-4 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)

程序名称：RMATRX STG1；目录编号：AAHA_v1_0；问题性质：本程序用于计算所有涉及束缚轨道（bound orbital）与连续轨道（continuum orbital）的单电子、双电子及多极径向积分，可为通用原子系统的电子与原子/离子散射、光电离或频率依赖性极化率计算提供所需的积分数据。束缚轨道以解析形式预先指定，连续轨道由本程序自行计算生成。计算得到的积分将存储于永久性磁带或磁盘文件中，供RMATRX STG2程序调用。本程序的各版本收录于曼德列数据（Mendeley Data）中的CPC数据库内，相关标识为：AAHA_v1_0；RMATRX STG1；DOI: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年）。
