Laboratory studies of X-ray emission from Fe L-shell transitions and their diagnostic utility
Celestial objects are often home to complex, dynamic, intriguing environments. High-resolution x-ray spectra from these sources measured by satellites such as the Chandra, XMN-Newton, the Solar Maximum Mission, and the soon-to-be-launched Astro-E2 provide a means for understanding the physics governing these sources. Especially rich is the x-ray emission from L-shell transitions in highly charged ions. The emissions is the source of a variety of diagnostics and benchmarked by laboratory data. In this paper we discuss laboratory measurements of Fe L-shell x-ray emission including wavelengths, relative and absolute excitation cross sections, and line ratios that provide diagnostics of temperature and density.
