Abstract

We use time-resolved laser-induced fluorescence to measure the lifetime of 186 Fe i levels with energies between 25 900 and 60 758 cm−1. Measured emission branching fractions for these levels yield transition probabilities for 1174 transitions in the range 225–2666 nm. We find another 640 Fe i transition probabilities by interpolating level populations in the inductively coupled plasma spectral source. We demonstrate the reliability of the interpolation method by comparing our transition probabilities with absorption oscillator strengths measured by the Oxford group [ Blackwell., Mon. Not. R. Astron. Soc. 201, 595– 602 ( 1982)]. We derive precise Fe i level energies to support the automated method that is used to identify transitions in our spectra.
