Abstract

The 12 C(p,γ)13 N reaction has a crucial role in the determination of 12 C/13 C isotopic ratio in RGB and AGB H-shell. This ratio is a sensitive indicator of stellar nucleosysnthesis and useful tool to trace the galactic evolution. However, existing models cannot reproduce the observed 12 C/13 C isotopic ratio due to the poorly constrained extrapolations at energies of interest. In the present work the measurements of 12 C(p,γ)13 N reaction cross section, which were performed at the Felsenkeller underground facility in Dresden (Germany) in the energy range 350-700 keV is presented. Prompt γ-rays associated with the formation of 13 N nuclide were analysed to determine the reaction cross section. The S-factor results are compared with some of the previous work and are in good agreement.

The 12 C(p,γ)13 N reaction has a crucial role in the determination of 12 C/13 C isotopic ratio in RGB and AGB H-shell. This ratio is a sensitive indicator of stellar nucleosysnthesis and useful tool to trace the galactic evolution. However, existing models cannot reproduce the observed 12 C/13 C isotopic ratio due to the poorly constrained extrapolations at energies of interest. In the present work the measurements of 12 C(p,γ)13 N reaction cross section, which were performed at the Felsenkeller underground facility in Dresden (Germany) in the energy range 350-700 keV is presented. Prompt γ-rays associated with the formation of 13 N nuclide were analysed to determine the reaction cross section. The S-factor results are compared with some of the previous work and are in good agreement.
