Experimental Investigation of the Hyperfine Structure of Tm I with Fourier Transform Spectroscopy Part B: in the NIR wavelength range from 700 nm to 2250 nm
In this study, we investigated the hyperfine structure of 43 spectral lines
of atomic thulium. We analyzed Fourier-transform spectra in the wavelength
range from 700 nm to 2250 nm, which corresponds to the wavenumber range from
14300 cm-1 to 4440 cm-1, respectively. The excited thulium atoms were generated
in a hollow-cathode lamp. As a result of this investigation, the
magnetic-dipole hyperfine constant A of 17 fine structure levels have been
determined experimentally, 14 of them for the first time. The magnetic-dipole
hyperfine constant values of the three remaining levels, reported in the
literature, differed significantly from the results of our determination.Comment: 12 pages, 6 gigure
