Scientific paper

We determine the solar abundance of iron from faint Fe I lines whose f-values have been determined in a branching ratio experiment and referenced directly to the Oxford f-value scale. The damping constants for the lines have been determined from a new theory for line broadening by collisions with neutral hydrogen and the abundances from individual lines have been determined by spectrum synthesis rather than by directly fitting the equivalent width of the lines. The derived abundance of iron is log N(Fe) = 7.54(sigma = 0.05) which is in good agreement with recent determinations based on both Fe I and Fe II lines lending further independent support to a low value of the photospheric iron abundance in agreement with the meteoritic value.
