用多组态Rayleigh-Ritz变分方法研究了B等电子序列(Z=8-13)的内壳层激发六重态1s2s2p2nl(n=2-7；L=S，p，d)和1s2p33p的能量、精细结构分裂、跃迁速率和寿命。一阶微扰理论考虑了质量极化效应和相对论修正。归属了类硼Na6+的高九层激发六重态系列6Se，o(M)和6Pe，o(M)(m=1-5)的组态结构。计算了6Pe(M)和6Po(M)(m=1-5)态之间电偶极跃迁的波长和跃迁速率。考虑了量子电动力学(QED)效应和高阶相对论修正，得到了更精确的跃迁波长。预测的跃迁波长与已有的理论和实验数据符合得很好。本文还报道并讨论了内壳层激发的六重态6Pe(M)(m=1-5)的寿命随核电荷数Z的增加。这些理论数据对实验中谱线的识别以及XUV和软X射线激光器的设计是有用的。
The energies, fine structure splittings, transition rates, and lifetimes of inner-shell excited sextet states 1s2s2p2nl, (n= 2–7;l= s, p, d) and 1s2p33p of the boron isoelectronic sequence (Z= 8–13) are investigated using the multi-configuration Rayleigh–Ritz variation method. The mass polarization effect and relativistic corrections are included by first-order perturbation theory. Configuration structures of the high-ninner-shell excited sextet series6Se,o(m) and6Pe,o(m) (m= 1–5) of boron-like Na6+ion are assigned. The wavelengths and transition rates of electric-dipole transitions between6Pe(m) and6Po(m) (m= 1–5) states are calculated. The quantum electrodynamics (QED) effects and higher order relativistic corrections are also considered to obtain more accurate transition wavelengths. The predicted transition wavelengths agree well with the available theoretical and experimental data. The lifetimes for the inner-shell excited sextet states6Pe(m) (m= 1–5) are also reported and discussed with the increase of nuclear charge number,Z. These theoretical data are useful for the identification of spectral lines in experiments and the design of XUV and soft X-ray lasers.
