Scientific paper

We report measurements of emission cross sections for iron L-shell 3-->2 lines in Fe23+ performed on the electron beam ion trap EBIT-II using a combination of a crystal spectrometer and the spare 6×6 element X-Ray Spectrometer microcalorimeter from the Astro-E X-ray satellite mission. Use of the microcalorimeter enables for first time the normalization of line emission cross sections, i.e., effective electron impact excitation cross sections that include radiative cascades, to the well-established cross section of radiative electron capture, thus allowing the normalization of relative line intensity measurements using crystal spectrometers.
