类铍铝离子的K_α跃迁特性研究

Transition properties of the Be-like K_α x-ray from Al X

我们报道了类Be的Al X最低40个能级的能级精细结构.利用基于多组态Dirac-Fock方程,我们给出了类Be的Al X的K_α跃迁的能级,波长,振子强度和能级寿命.研究表明,当前所得的理论计算结果与实验值以及其它理论值符合很好,同时对于分析已有的实验结果和指导拟开展的实验也有一定的意义.

We report calculations of energy levels and radiative rates for Kα transitions among the lowest 40 fine-structure levels in Be-like Al X. The wavelengths, oscillator strengths, radiative rates and lifetimes for all possible Kα transitions have been calculated using the multi-configuration Dirac-Fock method. The accuracy of the results is determined through extensive comparisons with existing laboratory measurements and theoretical results. These results can be used to analysis the previous experimental results and guide the design of the future experiments.
