Scientific paper
An analysis has been carried out using over 300 spectra of solar flares from both the XRP instrument on SMM and the SOX instrument on Hinotori. The helium-like iron and associated dielectronic satellite spectra were used in order to derive a revised ionization balance for Fe XXIV/Fe XXV. This is found to lie between the theoretical curves based upon ECIP ionization rates, and those using Lotz formalism, with a tendency to be closer to the former. An extension of the analysis to include Fe XXIII is subject to a somewhat larger uncertainty in the interpretation. However it indicates a similar effect for this ion. Using all three ions, a revised ionization balance for iron is presented.
