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M1 1s22s22p2P3/2—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.
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.
