Six proton-emitting states in Ne19 were studied through the inelastic scattering reaction H(Ne19,p)Ne*19(p)F18. Their energies and widths were derived from the protons detected at zero degree, while proton-proton angular correlations between the detector at zero degree and a segmented annular detector were used to determine their spin value. In addition to the known states, a new broad J=(1)/(2) resonance has been evidenced at Ex≈7.9MeV, ≈1.45MeV above the proton emission threshold. By introducing this resonance, the F18(p,α)O15 destruction rate in novae is significantly enhanced. This reduces the chance to observe the cosmic γ-ray emission of F18 from novae in space telescopes.
