Abstract
Knowledge of the astrophysical F(p,α)O rate is important for understanding gamma-ray emission from novae and heavy-element production in x-ray bursts. A state with E≃7.08 MeV in Ne provides an s-wave resonance and, depending on its properties, could dominate the F(p,α)O rate. By measuring a kinematically complete H(F,p)F excitation function with a radioactive F beam at the ORNL Holifield Radioactive Ion Beam Facility, we find that the Ne state lies at a center-of-mass energy of 665.3±1.7 keV (E =7077±2 keV), has a total width of 38.5±3.4 keV, and a proton partial-width of 15.8±1.6 keV.
