Goldberg, Leo ; Kopp, Roger A. ; Dupree, Andrea K. Abstract New laboratory measurements of the absolute f-values of Fe 1 lines by Corliss and Warner (1964) have made possible a new determination of the abundance of iron in the solar photosphere. Of the 628 lines used to obtain the curve of growth by the method of weighting functions, the majority fall on the linear branch of the curve and have lower excitation potentials in the range 3-5 eV. Since their mean optical depths of formation are as large as 0.6, it seems unlikely that the lines are significantly affected by departures from LTE. The resulting abundances appear to be independent of excitation potential, but seem to increase slightly with increasing wavelength. The average value of the derived abundance, log NF,/NH + 12 00 = 6.64, is in very good agreement with other modern determinations.
