Astrophys. 258 423 1992 1992A&A...258..423M atomic processes binaries: general binaries: spectroscopic line: formation molecular processes stars: emission-line, Be Results of an analysis of the intensities of the numerous Fe II emission and absorption lines present in the UV spectrum of KQ Puppis are reported. The self-absorption curve method developed by Friedjung and Muratorio (1987) is used to analyze the emission line intensities. The Fe II terms with chi from 0 to 11.5 eV are found to be populated according to a Boltzmann-type law with a mean excitation temperature of 9000 +/- 700 K. Above about 8 eV many terms show a population excess which can be attributed to a significant contribution of dielectronic recombination, and to fluorescence effects. The lower limit to the cool component mass loss rate is estimated at (4 +/- 2) x 10 exp -6 solar mass/yr.
