cds-question@unistra.fratomic-physicsThe Lande g-factor is an important parameter in astrophysical spectropolarimetry, used to characterize the response of a line to a given value of the magnetic field. The purpose of this paper is to present accurate Lande g-factors for states in BII, CI-IV, AlI-II, SiI-IV, PII, SII, ClIII, ArIV, CaI, TiII, ZrIII, and SnII. The multiconfiguration Dirac-Hartree-Fock and relativistic configuration interaction methods, which are implemented in the general-purpose relativistic atomic structure package GRASP2K, are employed in the present work to compute the Lande g-factors for states in BII, CI-IV, AlI-II, SiI-IV, PII, SII, ClIII, ArIV, CaI, TiII, ZrIII, and SnII. The accuracy of the wave functions for the states, and thus the accuracy of the resulting Lande g-factors, is evaluated by comparing the computed excitation energies and energy separations with the National Institute of Standards and Technology (NIST) recommended data. All excitation energies are in very good agreement with the NIST values except for TiII, which has an average difference of 1.06%. The average uncertainty of the energy separations is well below 1% except for the even states of AlI; odd states of SiI, CaI, TiII, ZrIII; and even states of SnII for which the relative differences range between 1% and 2%. Comparisons of the computed Lande g-factors are made with available NIST data and experimental values. Analysing the $LS$-composition of the wave functions, we quantify the departures from $LS$-coupling and summarize the states for which there is a difference of more than 10% between the computed Lande g-factor and the Lande g-factor in pure $LS$-coupling. Finally, we compare the computed Lande g-factors with values from the Kurucz database.2020A&A...639A..25Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/639/A25CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/639/A25https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/639/A25http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/639/A25https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/639/A25https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/639/A25http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/639/A25GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/639/A25/table5Lande g-fators for BIIg? lande g-factorsphys.atmol.landedoublenullablerecnoRecord number assigned by the VizieR team.
