Investigation of proton-induced reactions on Germanium isotopes

Abstract

The cross sections of the 70Ge(p,γ)71As and 76Ge(p,n)76As reactions have been measured in the energy range relevant for the astrophysical p-process (1.6–4.4 MeV). The proton beam was provided by the Van de Graaff and cyclotron accelerators of ATOMKI. The cross section was determined with the activation method by measuring the yield of the emitted γ-radiation following the β-decay of the reaction products. Experimental details and preliminary results are presented.
