LUNA: The 15N(p,\gamma )16O reaction study at low energies with a BGO detector

Abstract

The 15 N(p,γ) 16 O reaction has been intensively studied by the LUNA collaboration. In this contribution the measurements performed using a 4π-BGO detector and a solid target setup are described. The data, which are being analyzed, cover for the first time the entire Gamow peak for nova scenarios and investigate the Gamow energies for AGB and RGB stars. A detailed report of the target analysis and the procedure to determine the S-factor is described while the final results are still under evaluation. 11th Symposium on Nuclei in the Cosmos, NIC XI
