Photoionization Equilibrium Modeling of Iron L Line Emission

Abstract

We present models for the emission spectra of photoionized gases in the intermediate energy (0.5- 10 keV) X-ray region, including a detailed and up-to-date treatment of the atomic physics associated with the iron L shell. We discuss the general properties of iron L shell emission line strengths and recombination continuum emission and compare the strengths of these features with iron K shell emission and with the spectral features produced by other elements in the same energy range.
