本文报道了用电子束离子阱观察到的Ho（原子序数）、Er（68）和Tm（69）类Ag（）和类Cd（）离子的可见光谱。对于类银离子，我们发现了基态精细结构分裂之间的M1跃迁。对于类镉离子，几个M1跃迁的基态配置被确定。用相对论多体微扰理论和相对论CI +全阶近似计算了跃迁波长和跃迁几率。实验结果与计算结果的比较表明，两者吻合较好。
We present visible spectra of Ag-like () and Cd-like () ions of Ho (atomic number), Er (68), and Tm (69) observed with a compact electron beam ion trap. For Ag-like ions, prominent emission corresponding to the M1 transitions between the ground state fine-structure splittingis identified. For Cd-like ions, several M1 transitions in the ground state configuration are identified. The transition wavelength and the transition probability are calculated with the relativistic many-body perturbation theory and the relativistic CI + all-order approach. Comparisons between the experiments and the calculations show good agreement.
