Measurement of hyperfine structure constant of high excited levels in 169TmI
With a Tm-Kr hollow cathode discharge (HCD) lamp, we measured 21 transition lines of 169TmI by optogalvanic spectroscopy and determined the hyperfine structure constants of the upper levels, among them, seven are firstly reported to our knowledge. With the same HCD, the hyperfine structure constants of four excited levels are measured. by two-color resonance.
