Scientific paper

The line spectrum of the bright star HR 6000 in the wavelength range 3323-5316 A is analyzed on the basis of coudespectrograms obtained on IIIa-J emulsion with spectrum width 0.6 mm, projected slit width 22 microns, dispersion 12 A/mm, detection limit 10-15 mA, and wavelength accuracy + or 25 mA using the 1.5-m ESO telescope. A total of 433 identified and 92 unidentified lines are listed in a table. Important features include the absence of Si II, Si III, C II, and Hg II; the weakness of He I; the unambiguous identification of Fe I, Mn II, and P II; and the strength of Fe II, Ti II, and Cr II.
