        Abstract
        Since April 2005 a regularly updated stellar neutron cross section compilation is available online at http://nuclear-astrophysics.fzk.de/kadonis. This online-database is called the "Karlsruhe Astrophysical Database of Nucleosynthesis in Stars" project and is based on the previous Bao et al. compilation from the year 2000. The present version KADoNIS v0.2 (January 2007) includes recommended cross sections for 280 isotopes between (1)H and (210)po and 75 semi-empirical estimates for isotopes without experimental information. Concerning stellar (n,gamma) cross sections of the 32 stable, proton-rich isotopes produced by the p process experimental information is only available for 20 isotopes, but 9 of them have rather large uncertainties of >= 9%. The first part of a systematic study of stellar (n,gamma) cross sections of the p-process isotopes (74)Se, (84)Sr, (102)Pd, (120)Te, (130)Ba, (132)Ba, (156)Dy, and (174)Hf is presented. In another application KADoNIS v0.2 was used for an modification of a reaction library of Basel university. With this modified library p-process network calculations were carried out and compared to previous results.
