摘要
利用全相对论性多组态Dirac Fock平均能级(MCDF AL)方法系统计算了高剥离类镁离子互组合线3s21S0 3s3p3P1(Z=14～103)光谱跃迁的能级间隔和跃迁几率.计算中考虑了重要核的有限体积效应及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跃迁的互组合线跃迁几率和中性原子的电偶极E1的相当.在ICF和MCF高温高密度激光等离子体中,互组合线跃迁几率过程不容被忽视.
A fully relativistic multiconfiguration Dirac\|Fock method with Breit and QED corrections is used to calculate the spin\|forbidden 3s21S\-0\|3s3p\+3P\-1(Z＝14-103) transition energy level separations and transition probabilities for the Mg\|like ions. In the calculation, significant Breit and QED corrections are considered and the results are in agreement with recent experimental data and other theoretical values. The results show that the spin\|forbidden transition probabilities are in correspondence with those of E1 transitions and shouldn't be ignored in the laser plasma with high temperature created in ICF and MCF fusion.
