Abstract

EN In the present work 27 electronic energy levels of the holmium atom, with previously unknown energies, were identified for the first time. Experimental data were acquired with the method of laser spectroscopy in a hollow cathode discharge lamp, with laser induced fluorescence detection. Recorded patterns for 79 spectral lines of holmium in the spectral range 485–535 nm enabled determination of the hyperfine structure constants A and B for 23 odd-parity levels and 11 even-parity levels. For 31 levels the results are presented for the first time. The energy values for the previously unknown levels were determined, too.
