Abstract
The 3d photoionization and subsequent normal Auger decay processes in atomic strontium have been investigated. To understand the electron spectra following photoionization of a 3d electron, a series of ab initio computations, based on the multiconfiguration Dirac-Fock method, were performed. From the calculated photoionization and Auger decay amplitudes the relative photoionization cross sections were derived, together with the total and partial Auger decay widths and relative Auger intensities. Emphasis was placed on the effects of electron-electron correlations in the 3d hole state. The theoretical predictions were compared to the high-resolution synchrotron radiation-induced photoelectron and Auger electron spectra.
