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. Versions of this program held in the CPC repository in Mendeley Data AAHC_v1_0; RMATRX STG3; 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)
