Identification of Fe I lines in the ultraviolet solar spectrum

High-resolution ultraviolet echelle spectrograms of the Sun obtained from a rocket-borne spectrograph have been used for the identification of Fe I absorption lines in the wavelength range 1770--2020 A. Wavelength measurements, with a precision of approx.15 mA, are tabulated for 425 Fe I features, along with available laboratory wavelengths or predicted wavelengths calculated from atomic energy level data. The classification system of Moore has been extended to include possible additional multiples with 126 newly classified lines; 234 unclassified lines were observed and identified with laboratory Fe I spectra
