Abstract
Magnetic dipole and electric quadrupole transition probabilities have been calculated for all the transitions in the configurations 3d74s and 3d64s2 of Fe I. Configuration interaction has been included. A search with the Kitt Peak solar telescope has been made in sunspots for the lines corresponding to the strongest predicted transitions. Lines of the multiplets |${a}^{5}\,D-{a}^{3}\,P,{a}^{5}\,D-{b}^{2}\,F,\,\text{and}\,{a}^{5}\,D-{a}^{5}\,P$| have been tentatively identified. Their equivalent widths confirm the high solar iron abundance: log NFe = 7.5. The possible presence of [Fe I] lines in the absorption spectrum of Arcturus is also discussed.
