Analyzing power measurement for the 14 N(→p, γ) 15 O reaction at astrophysically relevant energies


Journal Article

The 14N(→p, γ)15O reaction has been investigated by measuring the angular distributions of its cross section and analyzing power using a 270-keV polarized proton beam. Calculations using a direct-capture-plus-resonance model were compared with the data. The results indicate the presence of γ transition amplitudes which were not considered in previous extrapolations of the astrophysical S factor to low energies. The impact on the zero-energy S factor of the 14N(→p, γ)15O reaction is discussed.
