Abstract
Knowledge of the 18F(p,a)15O and 18F(p,g)19Ne astrophysical reaction rates are important to understand -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 19Ne. We have examined the latest experimental measurements with radioactive and stable beams, collected all the structure information in the nucleus 19Ne and its mirror 19F, and made estimates of unmeasured 19Ne nuclear-level parameters. These parameters will be useful for future reaction rate calculations.
