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

## Description

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)
