Knowledge of the F18(p,α)O15 and F18(p,γ)Ne19 astrophysical reaction rates are important to understand γ-ray emission from nova explosions and heavy-element production in x-ray bursts. The rates for these reactions have been uncertain, in part due to a lack of a comprehensive examination of the available structure information in the compound nucleus Ne19. We have examined the latest experimental measurements with radioactive and stable beams, collected all the structure information in the nucleus Ne19 and its mirror F19, and made estimates of unmeasured Ne19 nuclear-level parameters. These parameters will be useful for future reaction rate calculations. © 2007 The American Physical Society.
