cds-question@unistra.fratomic-physicsWe present results for the electron-impact excitation of N-like Fe as part of the RmaX network. R-matrix theory using an intermediate-coupling frame transformation method is used to obtain level-resolved collision strengths. Separate calculations are performed using different target expansions. The first is a 215 level close-coupling calculation which has the 2s^2^ 2p^3^, 2s 2p^4^, 2p^5^, 2s^2^ 2p^2^ 3l, and 2s 2p^3^ 3l configurations while the second calculation also includes the levels from the 2s^2^ 2p^2^ 4l configurations for a total of 302 close-coupling levels. The effect of the additional resonant enhancement of the larger calculation is explored and compared with a previous IRON Project report and other, more recent, calculations. As a final comparison, we model an astrophysical plasma using the results of the present calculations and previous work.2007A&A...466..763Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/466/763CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/103/273 : IRON Project II IR collision strengths of C-like ionsJ/A+A/283/319 : IRON Project III B-like ionsJ/A+AS/108/1 : IRON Project V Collision strengths of O-like ionsJ/A+A/293/953 : IRON Project VI Fe II collision strengthsJ/A+A/293/967 : IRON Project VII Fe II radiative transitionsJ/A+AS/109/193 : IRON Project VIII Electron excitation of Ti-like ionsJ/A+AS/119/509 : IRON Project XVII Radiative transition in Fe IIIJ/A+AS/119/523 : IRON Project XVIII Electron impact for Fe IIIJ/A+AS/120/361 : IRON Project XIX Fe II radiative transitionsJ/A+AS/123/159 : IRON Project XXII C and O radiative ratesJ/A+AS/123/575 : IRON Project XXIII Fe XXII excitation rate coefficientsJ/A+AS/126/373 : IRON Project XXVII Fe IV collision strengthsJ/A+AS/131/499 : IRON Project XXIX Boron isoelectronic sequenceJ/A+AS/131/153 : IRON Project XXXI Fe XII electron excitationJ/A+AS/135/347 : IRON Project XXXV Fe XXIV & Fe XXV oscillator strengthsJ/A+AS/136/395 : IRON Project XXXVII Fe VI collision strengthsJ/A+AS/137/165 : IRON Project XXXVIII Fe XV fine-structure transitionsJ/A+AS/143/483 : IRON Project XLII Fe XXI electron impact excitationJ/A+AS/144/141 : IRON Project XLIII Fe V transition probabilitiesJ/A+AS/147/111 : IRON Project XLIV Fe VI trans. prob. & line ratioJ/A+AS/147/253 : IRON Project XLV Ar XIII, Fe XXI trans. probabilitiesJ/A+A/365/268 : IRON Project XLVII Ni III electron impact excitationJ/A+A/372/1078 : IRON Project XLIX Fe XX electron impact excitationJ/A+A/372/1083 : IRON Project L Fe XIX electron impact excitationJ/A+A/394/753 : IRON Project LI Fe IX electron impact excitationJ/A+A/408/789 : IRON Project LIII Fe XVII transition probabilitiesJ/A+A/413/779 : IRON Project LIV Fe XX transition probabilitiesJ/A+A/420/763 : IRON Project LV Ni II electron impact excitationJ/A+A/437/345 : IRON Project LIX Fe IV transition probabilitiesJ/A+A/448/779 : IRON Project LXI Fe IV radiative transitionsJ/A+A/457/721 : IRON Project LXII Fe XVIII allowed and forbidden trans.https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/466/763https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/466/763http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/466/763https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/466/763https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/466/763http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/466/763GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/466/763/energiesEnergy levels of the n=4 calculationPar[0/1] Parityphys.atmol.parityintrecnoRecord number assigned by the VizieR team.
