Landé [formula omitted] factors of the electronic levels of the holmium atom

Abstract

In the present work measurements of Landé gJ factors for some electronic levels of the holmium atom are presented. The measurements were performed with the use of the Zeeman effect of the hyperfine structure, observed with the method of laser spectroscopy in a hollow cathode discharge lamp placed in constant magnetic field, with laser induced fluorescence detection. Investigation of 69 spectral lines of holmium in the spectral range 490–670 nm enabled for the first time the determination of gJ factors for 15 levels belonging to the odd-parity configurations of Ho and 18 levels belonging to the even-parity configurations.
