Popis: In the present work measurements of Lande gJ factors for some electronic levels of the europium 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 54 spectral lines of europium in the spectral range 511–662 nm enabled for the first time the determination of gJ factors for 16 levels belonging to the odd-parity configurations of Eu and 4 levels belonging to the even-parity configurations. Moreover, 3 gJ values for levels belonging to the even-parity configurations, previously known from the literature, were corrected.
