Astrophysical reaction rate for F17(p,γ)Ne18 from the transfer reaction C13(O17,O18)C12 Academic Article uri icon


  • The asymptotic normalization coefficients of the bound states Jπ=(01+,21+,41+,22+) in O18 are extracted from the peripheral neutron transfer reaction C13(O17,O18)C12. They are then converted to their mirror states in Ne18, which are further used to evaluate the astrophysical S factor for the proton capture reaction F17(p,γ)Ne18. The elastic-scattering cross sections have been measured in both incoming and outgoing channels in order to extract the optical potentials needed for distorted-wave-Born-approximation calculations. The S factor is found to be S1-17(0)=2.17±0.37 keV b. The contribution of the direct capture rate to this reaction is estimated, and its consequences on the production of F18 at stellar energies in ONe novae are discussed. © 2014 American Physical Society.
