cds-question@unistra.fratomic-physicsThe primary motivation of this paper is to provide accurate atomic properties of F-like ions with Z=20-30, including energy levels, line strengths, static dipole polarizabilities, and lifetimes. In addition, a detailed analysis is also carried out to explore the convergence and uncertainties of our results. Large-scale B-spline relativistic configuration interaction calculations are carried out to generate the atomic properties of F-like ions. The radial parts of one-electron Dirac orbitals are obtained from the relativistic self-consistent field procedure in which the Breit Interaction and QED corrections (vacuum polarization and self-energy terms) are also included. A numerical method, called Emu CI, is adopted to decrease the size of CI matrix significantly without loss of much accuracy. Energy levels and line strengths for electric-dipole (E1), electric-quadrupole (E2), and magnetic-dipole (M1) transitions are provided for the 250 lowest levels of each system, showing a good agreement with available theoretical and experimental information. The static dipole polarizabilities and lifetimes for the ten lowest states are also reported. A statement for the convergence and uncertainties of our results is presented.2021A&A...645A.136Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/645/A136CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/645/A136https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/645/A136http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/645/A136https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/645/A136https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/645/A136http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/645/A136GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/645/A136/tableb1Energy levels relative to the ground state for F-like ions with Z=20-30ZAtomic numbermeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
