我们报告的大规模和严格评估的从头多组态Dirac-Hartree-Fock计算的波长和过渡率的“冠”，M1过渡4f F-2（5/2）o-F-2（7/2）o在Ag类离子。最近在Yb 23+和W 27+中观察到了这两个精细结构能级之间的跃迁，这构成了等电子序列中Z >= 62的基础项，其中W 27+对于聚变等离子体诊断可能非常重要。我们目前的Z = 50和94之间的序列的所有成员的值，这是由最近的实验值的极好的协议支持。强调了在理论模型中加入n = 3壳层的核价相关性的重要性。结果表明，这些禁线接近光谱的准确性。（减）
We report on large-scale and critically evaluated ab initio multiconfiguration Dirac-Hartree-Fock calculations of the wavelength and transition rate of the "coronal," M1 transition 4f F-2(5/2)o-F-2(7/2)o in Ag-like ions. The transition between these two fine-structure levels, which makes up the ground term for Z >= 62 in the isoelectronic sequence, has recently been observed in Yb23+ and W27+, where the latter could be of great importance for fusion plasma diagnostics. We present values for all members of the sequence between Z = 50 and 94, which are supported by excellent agreement with values from recent experiments. The importance of including core-valence correlation with the n = 3 shell in the theoretical model is emphasized. The results show close-to-spectroscopic accuracy for these forbidden lines. (Less)
