摘要
利用全相对论性多组态Dirac Fock平均能级 (MCDF AL)方法系统地计算了高离化类铍离子自旋禁戒 2s21S0 — 2s2 p3 P1(Z =10— 10 3)跃迁的能级间隔和跃迁概率 ,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 ,结果表明 :高原子序数的高荷电离子的自旋禁戒跃迁的跃迁概率和中性原子的电偶极E1的相当 ,在ICF和MCF高温激光等离子体中 ,自旋禁戒跃迁概率过程不容被忽视 .
A fully relativistic multiconfiguration Dirac\|Fock method with Breit and QED corrections is used to calculate the spin\|forbidden 2s 2 1S 0—2s2p 3P 1 ( Z =10—103) transition energy level separations and transition probabilities for the Be\|like ions. The results are in good agreements with recent experimental data and other theoretical values. The results show that the spin\|forbidden transition probabilities are in correspondence with these of E1 transitions and cannot be ignored in the laser plasma of high temperature in ICF and MCF fusions.
