Abstract

The F(p, γ)Ne reaction is important in stellar explosions, but its rate has been uncertain because of an expected 3 state in Ne that has never been conclusively observed. This state would provide a strong ℓ = 0 resonance and, depending on its excitation energy, could dominate the stellar reaction rate. We have observed this missing 3 state by measuring the H(F, p)F excitation function with a radioactive F beam at the ORNL Holifield Radioactive Ion Beam Facility. We find that the state lies at a center-of-mass energy of E = 599.8 ± 1.5 ± 2.0 keV (E = 4523.7 ± 2.9 keV) and has a width of Γ = 18 ± 2 ± 1 keV.
