Energies, Auger width and branching ratios of the core-excited triplet 1s2p3 3Po and 3Do resonances for a beryllium-like system

Abstract

The relativistic energies, Auger width and Auger decay branching ratios of the core-excited 1s2p3 3Po and 3Do states for the beryllium isoelectronic sequence (Z = 4–10) are studied using the saddle-point variational method and the saddle-point complex-rotation method. The total Auger width is obtained by coupling the important open channels and summing over the other channels. The oscillator strengths and transition rates are also calculated. Our results are compared with the available experimental and other theoretical results in the literature.
