Oscillator strengths and ground-state photoionization cross-sections have been computed for Mg + and Ca +. The polarization interaction between the valence electron and the core has been included in the calculations in a consistent manner. In some cases this interaction significantly changes the computed results. For many of the transitions considered, there exist no other published oscillator strengths.
