摘要：

The center-to-limb variation of equivalent widths of 198 Fe i lines in the spectral region 5500 to 7000 Å was studied with five photospheric models. The gf-values of Corliss and Warner (1964) were used in the analysis. The photospheric iron abundance was found to vary with excitation potential. This can be explained by a systematic error in the gf-values of high excitation lines and an error of 250 to 500K in the temperature of the arcs used for measuring the gf-values. Departures from LTE in the solar Fe i lines are also a possibility. The adopted photospheric abundance of iron, log(NFe/NH) is - 5.2. © 1969 D. Reidel Publishing Company.
