Abstract

Absolute gJ-values of sixty-eight Fe I and twelve Fe ii lines have been determined by shock-tube emission spectroscopy. These values extend our previous Fe I measurements to include somewhat weaker transitions and an expanded wavelength range ( A). Implications regarding recent determinations of iron abundances in the solar photosphere are considered.
