Abstract
Lifetimes of 12 excited levels of Fe I are calculated from Oxford oscillator strengths and compared with values measured by various experimenters. There is in general a poor agreement with all direct measures except those of Figger et al. which deviate from the calculated values by an average of 0.5 per cent, with dispersion of 5 per cent. It is concluded that the oscillator strengths of excited lines may be obtained more accurately by the absorption technique than by lifetime measurements.Keywords
