Abstract

We present visible spectra of Ag-like (4d104f4d^{10}4f) and Cd-like (4d104f24d^{10}4f^2) ions of Ho (atomic number Z=67Z=67), 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 splitting 4f5/24f_{5/2}--4f7/24f_{7/2} is 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.
