Underground investigation of the ¹⁴N(p,γ)¹⁵O reaction at low energy — •Alba Formicola — Institut für Experimentalphysik III, Ruhr-Universitüt Bochum, Germany

In view of the astrophysical importance of the ¹⁴N(p,γ)¹⁵O reaction for energy generation in massive stars, for the age of the globular cluster, and for the prediction of the solar neutrino energy spectrum, detailed measurements of this reaction over a wide energy range are needed. In order to investigate at very low energies this reaction, the LUNA collaboration has performed a high resolution gamma-ray measurement at the 400 kV underground accelerator facility installed at Laboratori Nazionali del Gran Sasso, exploiting the strong suppression of cosmic background. The final results of the measurement with solid state targets and the impact for the extrapolation to astrophysical energies will be presented.
