摘要
利用全相对论性多组态Dirac-Fock平均能级方法系统地计算了高剥离类钠离子3s2S-3d2D(Z=14~103)电四极矩E2光谱跃迁的能级间隔,跃迁几率和振子强度,计算中考虑了核的有限体积效应,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,计算结果表明:高原子序数的高荷电离子的电四极矩E2光谱跃迁的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,电四极矩E2光谱跃迁过程不容被忽视.
Abstract
A fully relativistic multiconfiguration Dirac-Fock method with Breit and QED corrections is used to calculate the 3s 3s2S-3d2D( Z =14~103)transition energy level separations, transition probabilities and oscillator strengths for the Na-like ions. In calculation, this paper considered significant Breit and QED corrections,the results are in good agreement with recent experimental data and other theoretical values. The results show that the electric quadruple transition probabilities are in correspondence with those of E1 transitions and can not be ignored in high temperature laser plasma in ICF and MCF Fusion.
