Abstract

On the basis of a fully relativistic multiconfiguration Dirac–Fock method, a systematic study has been carried out for the energies, radiative and non-radiative (Auger) decay processes of the core-excited states 1s2p3 for Be-like ions with Z=8–54. The energies and radiative transition rates are smoothly varying functions of Z. Auger rates do not change significantly with Z as the radiative rates do. Electron correlation effects on the energies and the radiative transition rates are investigated. Good agreement is found between our results and other theoretical data.
