# A new version of the general program to calculate atomic continuum processes using the r-matrix method

## Description

Title of program: A NEW VERSION OF RMATRX STG1 Catalogue Id: AAHF_v1_0 Nature of problem This program calculates all one-electron, two-electron and multipole radial integrals involving bound and continuum orbitals. These radial integrals 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 magnetic tape or disc file for use by A NEW VERSION of RMATRX STG2. Versions of this program held in the CPC repository in Mendeley Data AAHF_v1_0; A NEW VERSION OF RMATRX STG1; 10.1016/0010-4655(78)90004-8 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
