cds-question@unistra.fratomic-physicsWe present new large-scale R-matrix (up to n=4) and distorted wave (up to n=6) scattering calculations for electron collisional excitation of Fe XI. These data are needed for the analysis of soft X-ray spectra of astrophysical plasmas, where strong n=4-->n=3 transitions are present. As found in previous work on Fe X, Fe XII, and Fe XIII, resonances from within the n=4 levels and cascading from higher levels significantly increase the intensities of these lines. We provide a list of the strongest lines, many of which are unidentified. The present larger model produces intensities for decays from n=3 levels mostly consistent with our previous work, however significant enhancements for some lower levels are found, in particular for the 3s^2^3p^3^3d^5^D which can be used to measure electron temperatures in the solar corona with the Hinode/EIS spectrometer.2013A&A...549A..42Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/549/A42CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/422/731 : Fe X Benchmarking atomic data (Del Zanna+, 2004)J/A+A/430/331 : Atomic data from the IRON Project.
