Storage rings offer the possibility of measuring proton- and alpha-induced reactions in inverse kinematics. The combination of this approachwith a radioactive beamfacility allows, in principle, the determination of the respective cross sections for radioactive isotopes. Such data are highly desired for a better understanding of astrophysical nucleosynthesis processes like the p-process. A pioneering experiment has been performed at the Experimental Storage Ring (ESR) at GSI using a stable 96Ru beam at 9-11 AMeV and a hydrogen target. Monte-Carlo simulations of the experiment were made using the Geant4 code. In these simulations, the experimental setup is described in detail and all reaction channels can be investigated. Based on the Geant4 simulations, a prediction of the shape of different spectral components can be performed. A comparison of simulated predictions with the experimental results shows a good agreement and allows the extraction of the cross section.

The first version was an updated sequel to the previous Bao et al. [1] compilations from 1987 and 2000 for (n; g) cross sections relevant to Big Bang and s-process nucleosynthesis. The first update, KADoNiS v0.2, was published in 2006 [2]. It contained mainly Maxwellian averaged (n; g) cross sections relevant to the s-process, and some experimental charged particle induced reaction relevant to the p-process. After that a second update was presented in 2009 [3]. Recently, we started to collect and review all existing experimental data relevant for p-process nucleosynthesis and to provide a user-friendly database based on the KADoNiS framework. The p-process part of the KADoNiS database is currently being extended and will include all available experimental data from (p; g), (p;n), (p;a), (a,g), (a;n) and (a; p) reactions in or close to the respective Gamow window.
