In Atoms2020, 8, 23, doi:10.3390/atoms8020023, we reported on a complete optogalvanic (OG) spectrum of a discharge burning in a La&ndash, Ar gas mixture, in the spectral range 5610&ndash, 6110 Å, (17,851 to 16,364 cm&minus, 1). Now we are able to communicate further new energy levels, found via searching for laser-induced fluorescence lines when exciting unclassified lines from the OG spectrum. We were able to find 17 new levels, and for two further levels, the line list has extended. With the help of these 19 levels, we could classify 132 spectral lines.
