An m-representation approach to atomic structure: application to C I, N II, O III, F IV and Ne V

Abstract
Pilot calculations of atomic spectroscopy are reported, being based upon an m-scheme configuration interaction method in which Hartree-Fock wavefunctions are used to generate interaction integrals. The many-electron energy matrix is diagonalised using the Lanczos algorithm. The results obtained agree with comparable configuration interaction calculations encouraging the extension of the use of this method to molecular and other atomic systems.
