Abstract
We report new experimental Fe I oscillator strengths obtained by combining measurements of branching fractions
measured with a Fourier Transform spectrometer and time-resolved, laser-induced fluorescence lifetimes. This
study covers the spectral region ranging from 213 to 1033 nm. A total of 120 experimental log( ) gf -values coming
from 15 odd-parity energy levels are provided, 22 of which have not been reported previously and 63 of which
have values with lower uncertainty than the existing data. The radiative lifetimes for 60 upper energy levels are
presented, 39 of which have no previous measurements.
