Knowledge of the astrophysical 18F(p,α)15O rate is important for understanding gamma-ray emission from novae and heavy-element production in x-ray bursts. A state with Ex~=7.08 MeV in 19Ne provides an s-wave resonance and, depending on its properties, could dominate the 18F(p,α)15O rate. By measuring a kinematically complete 1H(18F,p)18F excitation function with a radioactive 18F beam at the ORNL Holifield Radioactive Ion Beam Facility, we find that the 19Ne state lies at a center-of-mass energy of 665.3+/-1.7 keV (Ex=7077+/-2 keV), has a total width of 38.5+/-3.4 keV, and a proton partial-width of 15.8+/-1.6 keV.
