中文摘要：

采用基于全相对论框架的多组态Dirac－Fock方法，系统研究了类Be离子（ Z＝8－54）内壳层激发态1s2s22p的能量、辐射退激发和Auger退激发过程。详细讨论了电子关联效应对相关结构和退激发过程的影响。结果表明，来自于n＝2和3壳层的电子关联效应最重要。另外，随着Z的增大，辐射退激发几率逐渐而平滑的增大，而Auger退激发几率的变化则不显著。本文计算结果与其它理论计算结果符合很好。

英文摘要：

Energies, radiative and Auger decay processes of the core-excited states 1s2s^22p of Be-like ions for Z=8-54 are studied using the fully relativistic Multi-configuration Dirac-Fock method.Electron correlations effects on structures and the decay processes of the core-excited states 1s2s22p of Be-like ions are discussed in detail .Re-sults show that electron correlations effects from n=2 and 3 subshells are important .Furthermore , the energies and radiative transition rates are smoothly varying function of Z , while Auger rates do not change significantly with Z as the radiative rates do .Good agreements are found between our results and the other theoretical results .
