abstract

  • The asymptotic normalization coefficients of the bound states J=(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,)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)=2.170.37 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.
