利用全相对论多组态Dirac-Fock方法系统地计算了高离化类铍离子的磁四极M2 2s^2 1S0—2s2p^3p2(Z=10—103)自旋禁戒跃迁的能级间隔、跃迁概率和振子强度,计算中考虑了重要核的有限体积效应,Breit修正和QED修正,所得结果和最近的实验数据以及理论值进行了比较,结果表明:高原子序数的高电荷离子(Z≥70)磁四极M2自旋禁戒跃迁几乎可以和中性原子的光学允许跃迁相比挑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该考虑其影响.
A full relativistic multi-configuration Dirac-Fock theory with quantum electrodynamical (QED) effect and Breit corrections is used to calculate the magnetic quadrupole M2 2s^2 1 S0--2s2p^3P2 (Z = 10--103) transition energy level, transition probabilities and oscillator strengths for Be-like ions for the first time. The results with Breit and QED corrections included are in good agreements with current experimental data and other theoretical values. The results show that the magnetic quadrupole transition probabilities of highly ionized atoms are comparable with those of neutral atomic allowed transitions and cannot be ignored in the laser plasma of high temperatures in ICF and MCF fusions. The effect of the magnetic quadrupole transition of highly ionsized atoms should be considered in the calculation of dielectronic recombination process, opacity, free path and so on.
