摘要：The energies, Auger widths and Auger decay branching ratios of the doubly core-excited 2s2p3 5,3S°, 3,1P° and 3,1D° resonances for Be-like oxygen are calculated using a saddle-point complex-rotation method. The relativistic corrections and mass polarization are included using the first-order perturbation theory. The partial Auger widths are obtained for the individual channels and the total Auger widths are obtained by coupling the important open channels and summing over the other channels. The Auger transition energies of these resonances are calculated and compared with the available experimental and other theoretical results in the literature. ? 2006 IOP Publishing Ltd.
