Description

The 12C(p,γ)13N reaction is relevant in several astrophysical scenarios, such as the early stages of the Bethe-Weizsäcker cycle of hydrogen burning and the production of 13C in stars on the asymptotic giant branch of the Hertzsprung-Russell diagram. Here new data on the 12C(p,γ)13N astrophysical S-factor at low energy, 0.1-0.5 MeV in the center of mass system are reported from an experiment in inverse kinematics. Titanium hydride targets were irradiated with an intensive 12C ion beam from the HZDR 3 MV Tandetron accelerator. The emitted γ-rays were detected in a lead shielded high-purity germanium detector also equiped with a cosmic ray veto. For target characterization, Nuclear Resonant Reaction Analysis (NRRA) was used with a 6.4 MeV 15N beam. The new data will contribute to the understanding of the creation of chemical elements in the precursors of core-collapse supernovae.
