Shake up processes in the 3d photoionization of Sr I and the subsequent Auger decay process

摘要

The shake-up processes accompanied by 3d photoionization and subsequent Auger decay processes of Sr I are studied using multi-configuration Dirac-Fock methods. General agreement is obtained with the experimental results for both the photoelectron and Auger electron spectra. The energy and relative intensity of the 5s → 6s shake-up accompanied by the 3d photoionization process are identified quantitatively.
