Investigation of nuclear physics properties for p process nucleosynthesis — •Martin Müller, Felix Heim, Yanzhao Wang, Svenja Wilden, and Andreas Zilges — Institute for Nuclear Physics, University of Cologne

More than 60 years after the ground breaking paper by Burbidge, Burbidge, Fowler and Hoyle [1] many questions about the nucleosynthesis of neutron deficient nuclei in the p process remain unsolved. While the number of p nuclei is small, the number of reactions involved in their production is extremely large, necessitating a detailed and precise theoretical description. This talk will provide a brief overview of our group’s contributions to the experimental determination of nuclear cross sections as well as studies of the underlying nuclear physics parameters such as the γ-ray strength function, the nuclear level density and the α-optical model potential. Recent experiments on proton- and α-induced reactions along with comprehensive comparisons with statistical model calculations will be presented [2-5].
