Direct cross section measurement for the 18O(p,γ)19F reaction at astrophysical energies at LUNA

Direct cross section measurement for the 18O(p,γ)19F reaction at astrophysical energies at LUNA

18O(p, γ)19F plays an important role in the AGB star scenarios. The low energy cross section could be influenced by a hypothetical low energy resonance at 95 keV and by the tails of the higher energy broad states. The 95 keV resonance lies in the energy window corresponding to the relevant stellar t...
