cds-question@unistra.fratomic-physicsUsing a combined configuration interaction and many-body perturbation theory approach, we calculate the level energies of 1s^2^2l^q^ and 1s^2^2l^q-1^3l' (1<=q<=8) complexes in iron and nickel ions. Comparison of 1s^2^2l^q^ energies with experimental results shows that the calculation is accurate to within ~0.15eV for these levels. The accuracy of 1s^2^2l^q-1^3l' energies can be slightly worse, at ~0.5eV. The theoretical wavelengths of 2->3 transitions of iron ions are compared with the published experimental measurements, and discrepancies are found to be mostly within {+/-}10m{AA}. Similar accuracy is expected for wavelengths of nickel ions. Such accuracy is a significant improvement over that obtainable with standard configuration interaction methods. A complete table of 2l->3l' transition wavelengths of all L-shell ions of iron and nickel is presented.2005ApJS..156..105Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/156/105CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/156/105https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/156/105http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/156/105https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/156/105https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/156/105http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/156/105GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJS/156/105/table3Combined CI and MBPT energies of 1s^2^2l^q^ and 1s^2^2l^q-1^3l' states for L-shell Fe and Ni ionsrecnoRecord number assigned by the VizieR team.
