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