Abstract
Five emission lines in the wavelength region 6122-6132 Angstrom in the spectrum of eta Carinae are identified as the 4d (5)D4f(5)F multiplet of Mn II. These are the only high-excitation lines of Mn II present i n the spectrum. The upper levels of the multiplet are most likely popu lated through photoexcitation by an accidental coincidence in waveleng th between the ultraviolet multiplets UV 15 of Mn II and UV 5 of Si II . Improved laboratory wavelengths for the Mn II lines are presented.
