Inelastic F17(p,p)F17 scattering at Ec.m.=3 MeV and the O14(α,p)F17 reaction rate

Document Type


Publication Date



The O14(α,p)F17 reaction is an important trigger reaction leading to the αp process in x-ray bursts. The inclusion of reaction channels populating excited F17 levels may significantly increase the calculated O14(α,p)F17 reaction rate. A radioactive F17 beam was used at the Oak Ridge National Laboratory Holifield Radioactive Ion Beam Facility to search for a Ne18 resonance at Ec.m.(F17+p)3.1 MeV that had been previously suggested to decay strongly to the first excited level in F17. No evidence, however, of inelastic F17+p scattering was observed at this energy, and an upper limit of ∼10 mb has been set on the inelastic-scattering cross section. © 2010 The American Physical Society.
