目标。在本文中，我们报告的能级和辐射率的过渡在钴xi的计算。方法.采用通用相对论原子结构程序包（GRASS）和柔性原子程序（FAC）计算能级和辐射率。结果本文报道了Co xi最低287个能级的能量，包括（1s22s22p6）3s23p5，3s3p6，3s23p43d，3s3p53d，3s23p33d2和3s23p44s组态。此外，辐射率和振子强度在所有电偶极（E1）跃迁f ≥ 10 −5的这些能级中被报道，磁偶极（M1），电四极（E2）和磁四极（M2）跃迁的类似结果仅在f ≥ 10 −8的能级中被报道。与文献中的可用结果进行比较，并评估当前数据的准确性。最后，还列出了所有激发能级的寿命，尽管目前只能测量其中一个能级。
Aims. In this paper we report calculations for energy levels and radiative rates for transitions in Co xi. Methods. The General purpose Relativistic Atomic Structure Package (grasp) and the Flexible Atomic Code (fac) have been adopted for the calculations of energy levels and radiative rates. Results. Energies for the lowest 287 levels of Co xi, including those among the (1s 2 2s 2 2p 6 )3 s 2 3p 5 ,3 s3p 6 ,3 s 2 3p 4 3d, 3s3p 5 3d, 3s 2 3p 3 3d 2 , and 3s 2 3p 4 4s configurations, are reported. Additionally, radiative rates and oscillator strengths are reported for all electric dipole (E1) transitions with f ≥ 10 −5 among these levels, and similar results for magnetic dipole (M1), electric quadrupole (E2), and magnetic quadrupole (M2) transitions are reported only for those with f ≥ 10 −8 . Comparisons are made with the available results in the literature, and the accuracy of the present data is assessed. Finally, lifetimes for all excited levels are also listed, although measurements are presently available for only one of these.
