cds-question@unistra.fratomic-physicsEffective collision strengths are presented for transitions from the 16 states of the 3d(5) configuration to the higher lying states belonging to the 3d(4)4s and 3d(4)4p configurations of Fe IV. Collision strength calculations performed with 108 coupled states (in LS-coupling) using the parallel R-matrix code PRMAT are used to determine the effective collision strengths by averaging them over a Maxwellian temperature distribution for the electrons. Each of the LS term level is assigned a label ranging from 1 to 108. Note; 1 to 16 refers to states associated with the 3d(5) configuration; 6S, 4G, 4P, 4D, 2I, 2D3, 2F2, 4F, 2H, 2G2, 2F1, 2S, 2D2, 2G, 2P and 2D1. Effective collision strengths data for 11 temperatures are presented (non-zero values) for electron temperatures ranging from ~2000 to 1000000K (i.e. log10(T)=3.3 to log10(T)=6.0).2006A&A...446.1185Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/446/1185CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/126/373 : IRON Project XXVII.
