采用全相对论多组态Dirac-Fock方法，对高离化类镁离子的磁四极3s21 S0-3s3 p 3 P2（Z＝20～103）自旋禁戒跃迁的能级间隔、跃迁波长、跃迁概率和振子强度等光谱跃迁参数进行了系统计算，计算中考虑了重要核的有限体积效应、Breit修正和QED修正，所得结果和最近已有的实验数据进行了比较。结果表明，高原子序数的高电荷离子（ Z≥70）磁四极自旋禁戒跃迁几乎可与中性原子的光学允许跃迁相比拟，不仅在天体等离子体中，在ICF和MCF高温激光等离子体中，磁四极自旋禁戒跃迁和其他自旋禁戒跃迁（磁偶极、电四极）一样不容忽视，在双电子复合、不透明度、自由程等理论计算中应考虑其影响。

A full relativistic multi-configuration Dirac-Fock theory with quantum electro-dynamical (QED) effect and Berit correction was employed to calculate the magnetic quadrupole 3s2 1 S0-3s3p 3 P2 (Z= 20-103) transition energy level intervals ,transition wavelengths ,transition probabilities and oscillator strengths for Mg-like ions . The results ,which consider the finite volume size effect ,Breit and QED corrections ,were used for comparsing with the recent experimental data .The results show that the mag-netic quadrupole transition probabilities of highly ionized atom ions are in accordance with those of neutral atomic allowed transitions and cannot be ignored in the laser plas-ma of high temperature in ICF and MCF fusions .The effects of the magnetic quadrupole transition of highly ionized atom ions should be considered in the calculation of dielec-tronic recombination process ,opacity ,free path and so on .
