“…This has been done for all four measured spectra, i.e., the Tm-Ar and Tm-Ne spectra in each case measured with a current of 50 or 70 mA. The extracted portions of experimental spectra of the lines then were fitted using the computer program Fitter (Zeiser et al 2022). Voigt profile functions for each HFS component with intensity ratios corresponding to the theoretical intensities have been applied…”

The hyperfine structure of 40 spectral lines of singly ionized thulium (Tm ii) in emission spectra from a hollow cathode discharge lamp measured with a Fourier transform spectrometer in the wavelength range from 335 to 2345 nm has been investigated. As a result of the analysis, the magnetic dipole hyperfine structure constants A for 27 fine structure levels of Tm ii were determined for the first time. In addition, the values of two magnetic dipole hyperfine structure constants A from the literature were declared incorrect, and the corrected values were given.

“…The standard deviation of the mean based on a sample s A from the results of the four different measurements, 2. The fitting uncertainty ΔA Fitter returned by the program Fitter (see Zeiser et al 2022), and 3. The uncertainty ΔA fixed of the magnetic dipole HFS constant A, which has been fixed during the fit:…”
