Abstract
We perform a systematic study of photoionization with excitation and double photoionization of [Formula Presented] He, and [Formula Presented] using the convergent close-coupling formalism. The present calculations cover the photon energy range from the double-ionization threshold to 10 keV where the results go over continuously to the nonrelativistic limit of infinite photon energy. By consideration of scaling properties, tested by application to [Formula Presented] accurate nonrelativistic results for photoionization with excitation to arbitrarily high n and double photoionization may be obtained for all heliumlike targets.
