Auger width and branching ratios of the core-excited triplet 1s2p^(33)P0、~3D^0及2s2p^(33)D^0 resonances for beryllium-like system

采用鞍点变分方法和鞍点复数转动方法并考虑相对论修正和质量极化效应,计算了类铍离子内壳激发态1s2p3 3P0、3D0和内壳双激发态2s2p3 3D0的俄歇宽度、俄歇分支率和俄歇电子能量.同时还对1s22p2 3Pe态到1s2p3 3P0、3D0态(Z=4~10)的振子强度和辐射跃迁率进行了计算,计算结果与其他理论结果以及实验数据符合得很好.

The Auger width, Auger decay branching ratios and Auger channel energies of the core-excited 1s2p^3 ^3P^0、^3D^0 and doubly-core-excited 2s2p^3 ^3D^0 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 relativistic corrections and the mass polarization are also included using first-order perturbation theory. These results are compared with the available experimental and other theoretical results in the literature.
