摘    要:采用相对论量子力学GRASP2程序,扩展平均能级EAL模型,有限核模型,考虑Breit和QED的高阶微扰修正,系统地研究了类硼等电子序列磁偶极M11s22s22p2P3/2—2P1/2(Z=10~100)光谱跃迁的精细能级结构间隔,跃迁概率和振子强度,所得结果和最近的实验数据及理论计算值进行了比较。计算结果表明:在ICF高温高密度激光等离子体中磁偶极矩M1跃迁几率过程不容被忽视。

关 键 词:磁偶极矩M1  精细能级结构间隔  跃迁概率  振子强度

Abstract:The fully relativistic mechanics (GRASP2) with Breit and QED corrections is used to calculate the magnetic dipole M1 1s22s22p2P3/2—2P1/2(Z=10~100) transition energy level intervals and transition probabilities and oscillator strengths of the ground state boron isoelectronic sequence. In calculation, we considered the significant nuclear volume effect and Breit and QED correction effects so that excellent comparison was obtained throughout the range of Z. The results are in excellent agreement with those of observations, and show no systematic errors. The relation of our results to those of other recent calculations is investigated.
Keywords:Magnetic dipole M1  Fine-structure energy level intervals  Transition probability  Oscillator strengths
