(α,γ) reaction studies relevant to the astrophysical p-process nucleosynthesis
In the framework of this project we propose the study of (α,γ) reactions relevant to the astrophysics p-process nucleosynthesis. Specifically, we are aiming to the experimental and theoretical investigation at astrophysical beam energies selected (α,γ) reactions, such as: 73Ge(α,γ)77Se and 102Pd(α,γ)106Cd. The goal of the study, is by using the 4π NaI(Tl) detector to provide experimental data in previously unexplored energy regions or in beam energies were the existing experimental information is insufficient for setting firm constrains of the theoretical model calculations. Accordingly, we suggest the study of the excitation function of the above mentioned reactions for α-beam energies between 6-15 MeV, as provided by Dynamitron Tandem Laboratorium (DTL) of the Ruhr-Universität Bochum and by adopting an energy step of the order of 0.5 MeV.
