Abstract

Laser spectroscopy and optogalvanic detection was applied to investigate up to now unclassified or even unknown spectral lines of atomic lanthanum (La I). The exciting laser light had wavelengths between 4300 and 6800 Å. We report the discovery of seven new energy levels. One additional level turned out to be already known, but with wrong angular momentum. Altogether 53 spectral lines could be classified as transitions of these eight levels.
