cds-question@unistra.fratomic-physicsWe report calculations of energy levels and radiative rates for 1300 fine-structure levels generated from 189 configurations of Be-like Nickel. The General Purpose Relativistic Atomic Structure Program (GRASP2), developed by the I.P. Grant group in 1989 and partly improved by our group, is adopted in the calculations of energy levels and radiative rates. Our calculations are compared with those of other numerical methods and experiments so that their accuracy can be assessed. Additionally, the wavelengths, oscillator strengths, and radiative rates (for a given radiative rate and level structure, it is then easy to derive the line strength) a re reported for all electric dipole (E1), electric quadrupole (E2), magnetic dipole (M1) and magnetic quadrupole (M2) transitions among these levels. Finally, the lifetimes of all excited levels are reported.2008A&A...488.1155Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/488/1155CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/460/959 : NiXIX radiative and excitation rates (Aggarwal+, 2006)J/A+A/475/393 : NiXI radiative and excitation rates (Aggarwal+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/488/1155https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/488/1155http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/488/1155https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/488/1155https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/488/1155http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/488/1155GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/488/1155/table1The level energies of NiXXV ionIndexIndexmeta.idintrecnoRecord number assigned by the VizieR team.
