利用基于完全相对论R-矩阵方法的Dirac原子R-矩阵方法，详细计算了基态CV离子在KLL和KLM共振能区的部分和全部光复合截面。同时，根据计算的Kll和KLm共振态到1s2nL(n=2，3，L=S，p，d)末态的跃迁能和几率，对每个光复合通道中的主共振线进行了分类。这些计算的有效性是通过与以前发表的实验和理论数据进行比较来评估的。目前的计算结果与采用不同方法得到的结果很好地吻合，证实了本结果的准确性。此外，研究还发现，对于KLL谐振器，阻尼效应可以忽略不计，而对于KLM谐振器，则不能忽略。
The partial and total photorecombination cross sections of the ground-state CV ion in the KLL and KLM resonant energy regions were calculated in detail by using the Dirac atomic R-matrix code based on a fully relativistic R-matrix method. Meanwhile, the principal resonant lines in each photorecombination channel have been classified according to the calculated transition energies and probabilities from the KLL and KLM resonant states to the 1s 2 nl (n= 2, 3 and l= s, p, d) final states. The validity of these calculations is assessed by comparison with previously published experimental and theoretical data. The good agreement between the present calculated results and those obtained using different approaches confirms the accuracy of the present results. In addition, it is found that the damping effect can be neglected for the KLL resonant, but not for the KLM resonant.
