Abstract
The integro-differential equations for electron-ion scattering processes are solved for bound-state energies of the compound system, a method called frozen-cores approximation when introduced by Wilson and Seaton (1972). The solutions are used to calculate oscillator strengths. The core states chosen in the present paper are such that the results should be comparable with the recent multiconfiguration Hartree-Fock calculations for Mg by Froese Fischer (1975).Keywords
