摘　　要：利用全相对论性多组态Dirac-Fock平均能级(MCDF-EAL)方法系统地计算了类镁离子3s2 1S0-3s3d1D2电四极矩E2光谱跃迁的能级间隔,跃迁几率和振子强度,计算中考虑了重要的核的有限体积效应,Breit修正和QED修正,所得结果和最近的实验数据及理论计算值进行了比较.A fully relativistic multiconfiguration Dirac-Fock method with Breit and QED corrections is used to calculate the 3s^2^1S0-3s3d ^1D2 E2 transition energy level separations, transition probabilities and oscillator strengths for the Mg-like ions. In calculation, we consider significant Breit and QED corrections, the results are in good agreements with recent experimental data and other theoretical values. The results show that the electric qua-drupole E2 transition probabilities are in correspondence with these of E1 transitions.
