cds-question@unistra.fratomic-physicsA general formalism to include experimental reaction cross sections into calculations of stellar rates is presented. It also allows us to assess the maximally possible reduction of uncertainties in the stellar rates by experiments. As an example for the application of the procedure, stellar neutron capture reactivities from KADoNiS v0.3 are revised and the remaining uncertainties shown. Many of the uncertainties in the stellar rates are larger than those obtained experimentally. This has important consequences for s-process models and the interpretation of meteoritic data because it allows the rates of some reactions to vary within a larger range than previously assumed.2012ApJ...755L..10Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/755/L10CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/738/143 : Ground-state contributions around s-process (Rauscher+, 2011)J/MNRAS/404/1529 : s-process in low-metallicity stars (Bisterzo+, 2010)http://www.kadonis.org/ : Karlsruhe Astrophysical Database of Nucleosynthesishttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/755/L10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/755/L10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/755/L10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/755/L10https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/755/L10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/755/L10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJ/755/L10/table1Revised uncertainty factors of stellar (n,{gamma}) reactivities at 11 plasma temperatures -- updated version from erratum published in 2018, ApJL, 864, L40recnoRecord number assigned by the VizieR team.
