For the element niobium, whose energy level structure was considered to be well known regarding the low-lying levels, the energy values of four low-lying levels, listed in Moore's tables of atomic energy levels, were found to be incorrect. The correct positions of these levels have been revealed, and, additionally, two new levels have been detected using laser-induced fluorescence spectroscopy in the wavelength region from 470 to 505.
