| 摘 要： | 采用全相对论量子力学GRASP2程序和平均能级AL模型，在核的有限体积效应、Breit和QED效应的高阶扰动基础上，系统地计算了类铍离子组态磁偶极M1、磁四极胞和磁八极M3光谱跃迁波长，跃迁几率和振子强度，所得结果和最近的实验数据及理论计算值进行了比较，结果表明：高原子序数的高荷电离子的磁多级矩的跃迁几率和中性原子的电偶极矩相当，在ICF和MCF高温激光等离子体中，磁多级矩的跃迁几率过程不能被忽视．

| Abstract: | A fully relativistic multiconfiguration Dirac-Fock method with Breit and QED corrections was used to calcula- te transition energy level separations, transition probabilities and oscillator strengths for the Be-like ions. In the calculation, the significant Breit and QED corrections were considered. The results were compared with recent experimental data in good agreements and other theoretical values. The results show that the magnetic multidipol6 transition probabilities were in correspondence with these of E1 transitions and can not be ignored in the laser plasma of high temperature in ICF and MCF Fusion. |
