cds-question@unistra.fratomic-physicsMulticonfiguration Dirac-Hartree-Fock (MCDHF) calculations and relativistic configuration interaction (RCI) calculations are performed for states of the 3s^2^3p^2^, 3s3p^3^ and 3s^2^3p3d configurations in the Si-like ions Ti IX - Ge XIX, Sr XXV, Zr XXVII and Mo XXIX. Valence and core-valence electron correlation effects are accounted for through large configuration state function expansions. Calculated energy levels are compared with data from other calculations and with experimental data from the reference databases. Lifetime and transition rates along with uncertainty estimations are given for all ions. Energies from the calculations are in excellent agreement with observations and computed wavelength are almost of spectroscopic accuracy, aiding line identification in spectra.2016A&A...585A..26Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/585/A26CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/105/245 : Stark broadening Al XI and Si XII (Dimitrijevic+ 1994)J/A+AS/129/155 : Si XI + Si XIII lines Stark broadening (Dimitrijevic+ 1998)J/ApJS/121/591 : Oscillator Strengths for Si VI (Coutinho+, 1999)J/A+A/423/397 : Stark broadening of Si V (Ben Nessib+, 2004)J/A+A/508/1527 : Si II Radiative transition rates (Bautista+, 2009)J/MNRAS/387/871 : Si VI atomic data and broadening effect (Hamdi+, 2008)J/A+A/522/A103 : Si XI K-shell energy levels and radiative rates (Wei+, 2010)J/A+A/566/A105 : Si IX K-shell energy levels and transitions (Wei+, 2014)J/A+A/559/A100 : Boron isoelectronic sequence data (Jonsson+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/585/A26https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/585/A26http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/585/A26https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/585/A26https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/585/A26http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/585/A26GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/585/A26/table2Calculated and observed excitation energies in cm-^1^n_E(obs)Note on E(obs) (3)meta.notecharrecnoRecord number assigned by the VizieR team.
