Scientific paper

The authors revised the solar iron abundance from photospheric Fe I lines using two scales of oscillator strengths gf. The first one is Oxford high-precision laboratory measurements of Fe I transition probabilities. The second scale recently obtained in a hollow-cathode experiment by Bard et al. differs from the former by 0.03 dex in the absolute scale. The abundance values A = 7.64±0.04 and A = 7.50±0.07 respectively were determined. In order to explain the puzzle why gf of both scales agree but abundances deviate the authors have analysed the possible sources of errors in determinations of solar abundance.
