cds-question@unistra.fratomic-physicsRecent radiative lifetime measurements accurate to +/-5% using laser-induced fluorescence (LIF) on 43 even-parity and 15 odd-parity levels of CeII have been combined with new branching fractions measured using a Fourier transform spectrometer (FTS) to determine transition probabilities for 921 lines of CeII. This improved laboratory data set has been used to determine a new solar photospheric Ce abundance, log{epsilon}=1.61+/-0.01 ({sigma}=0.06 from 45 lines), a value in excellent agreement with the recommended meteoritic abundance, log{epsilon}=1.61+/-0.02. Revised Ce abundances have also been derived for the r-process-rich metal-poor giant stars BD+17 3248, CS 22892-052, CS 31082-001, HD 115444, and HD 221170. Between 26 and 40 lines were used for determining the Ce abundance in these five stars, yielding a small statistical uncertainty of {+/-}0.01dex similar to the solar result. The relative abundances in the metal-poor stars of Ce and Eu, a nearly pure r-process element in the Sun, matches r-process-only model predictions for solar system material. This consistent match with small scatter over a wide range of stellar metallicities lends support to these predictions of elemental fractions. A companion paper includes an interpretation of these new precision abundance results for Ce as well as new abundance results and interpretation for Pr, Dy, and Tm.2009ApJS..182...51Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/182/51CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AZh/84/997 : Abundances of Sr, Y, Zr, Ce and Ba (Mashonkina+, 2007)J/ApJS/182/80 : Rare earth abundances (Sneden+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/182/51https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/182/51http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/182/51https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/182/51https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/182/51http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/182/51GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJS/182/51/table2Atomic transition probabilities for CeII (Z=58) organized by increasing wavelength in airrecnoRecord number assigned by the VizieR team.
