摘　　要：用多组态Dirac-Fock和相对论组态相互作用的扩展优化能级方法,在计算中包含了Breit相互作用,真空极化,自能以及有限核质量修正,计算了核电荷数从Z=6～80的类铍离子等电子序列的1s^22s2p^3P_(1,2)的精细结构能级,磁偶极跃迁几率和振子强度.结果与目前可靠的结果在其不确定度范围内符合得很好,另外也得到一些与其他早期理论计算不同的结果.The extended optimal level version of the multiconfiguration Dirac-Fock （MCDF） and relativistic configuration interaction （RCI） calculation with the inclusion of Breit interaction, vacuum polarization, self energy and finite nuclear mass corrections in the active interaction approach has been used to calculate the fine-structure intervals, transition rates and oscillator strengths for the magnetic dipole of the interval transitions among 1s^2 2s2p^3P1,2 levels of ions in the beryllium isoelectronic sequence with nuclear charge ranging from Z= 6 to 80. A comprehensive comparison of present results is performed with other recent available values. The corresponding present results are in good agreement with reliable values within the inaccuracy of them, and some differences are found with other calculative results.
