Abstract

EN In the present work the experimentally determined values of Landé gJ factors for 20 odd-parity electronic levels of atomic terbium are presented. The Zeeman splitting of the hyperfine structure was investigated using the method of laser induced fluorescence in a hollow cathode discharge lamp in a constant magnetic field. All of the values were determined for the first time, by the analysis of 32 spectral lines, recorded in the spectral range between 492 and 609 nm. Moreover, the gJ factors for 15 even-parity energy levels, reported in the available literature, were verified.
