The Astrophysical Journal, 970(1), 23.0004-637X1538-4357http://dx.doi.org/10.3847/1538-4357/ad47b7https://hdl.handle.net/20.500.12713/7035The 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.eninfo:eu-repo/semantics/openAccessLife Time MesasurementsEnergy-LevelsWavelengthsArticle9701112WOS:0012698224000012-s2.0-85198601026Q110.3847/1538-4357/ad47b7Q1
