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