Magnetic Dipole Hyperfine Constants of 15 Energy Levels in ${}^{169}$Tm II Determined by Collinear Laser Fluorescence Spectroscopy

Hendrik Bodnar, Kristian König, Wilfried Nörtershäuser

We present measurements of the hyperfine structure, transition frequencies and relative intensities in 14 lines of 169Tm+ ions starting from the $4f^{13}({}^2\!F^o_{7/2})6s_{1/2} (…
