InelasticF17(p,p)F17scattering atEc.m.=3 MeV and theO14(α,p)F17reaction rate

The 14O( ,p)17F reaction is an important trigger reaction leading to the p process in x-ray bursts. The inclusion of reaction channels populating excited 17F levels may significantly increase the calculated 14O( ,p)17F reaction rate. A radioactive 17F beam was used at the Oak Ridge National Laboratory Holifield Radioactive Ion Beam Facility to search for a 18Ne resonance at Ec.m.(17F + p) 3.1MeV that had been previously suggested to decay strongly to the first excited level in 17F. No evidence, however, of inelastic 17F + p scattering was observed at this energy, and an upper limit of 10 mb has been set on the inelastic-scattering cross section.
