硼基态等电子序列磁偶极M1精细结构间隔和光谱跃迁参数

采用全相对论量子力学GRASP2程序,选取三电子组态1s22s22p, 1s22s2p2, 1s22p3,有限核费米模型,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 1s22s22p*"2P3/2-2P1/2( 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,计算结果表明1s22s2 2p和1s22p3组态之间存在明显的非动力学组态相关,采用三电子组态计算的精细能级结构间隔较单电子组态的计算结果有了显著的改善.

Abstract

The fully relativistic quantum mechanics(GRASP 2) with Breit and QED corrections is used to calculate the magnetic dipole M1 1s 22s 22p? 2P 3/2 - 2P 1/2 (Z=10～100) transition energy level intervals and transition probabilities and oscillator strengths of the ground state boron isoelectronic sequence. In calculation, we consider the significant nuclear volume effect. The three configurations 1s 22s 22p, 1s 22s2p 2, 1s 22p 3 were used. Breit and QED correction effects were treated as second order perturbations. Excellent comparison was obtained throughout the range of Z. The results are in excellent agreement with observations where these exist, and show no systematic errors with Z. The relation of our results to those of other recent calculations is investigated.
