Abstract
The high resolution (R approximate to 10(4)) near-ultraviolet IUE spec trum of the peculiar post Asymptotic Giant Branch (post-AGB) supergian t HD 101584 (FOIape) has been analyzed. In the wavelength range betwee n 2500 and 3000 Angstrom A, 291 out of 332 absorption features are ide ntified. The main contribution comes from FeII, CrII and MnII. Most of the absorption features are blends from several absorption lines. Thi s is mainly due to the intrinsic broad line profiles in the spectrum o f HD 101584 in combination with the many absorption lines which occur in the UV for a F-type spectrum. The list compiled gives for all measu red absorption features between 2500 and 3000 Angstrom A the measured central wavelength of the core of the profile, the equivalent width of the profile if this could be determined, the depth of the profile, an asymmetry factor, a quality factor and Lists the transitions which ar e responsible for the feature. An analysis of the radial velocities of the absorption profiles will be given in a separate paper.
