| Popis: | Laser Induced Fluorescence Spectroscopy (LIF) and Optogalvanic Spectroscopy (OG) were used for the investigation of the Zeeman hyperfine structures of 26 spectral lines of La I in the wavelength range between 569.7 and 665.4 nm. As a source of free La atoms a hollow cathode discharge lamp was used. The spectra were recorded in the presence of a magnetic field of about 800G produced by a permanent magnet for two linear polarizations of the exciting laser light. As a result of the study, we determined for the first time the Lande g J - factors of 20 levels of La I. For several other levels the Lande g J - factors were re-investigated and determined with higher precision. |
