Abstract

19Ne plays an important role in astrophysical environments, such as affecting the 18F(p, γ)19Ne and 18F(p,α)15O reaction rates which impact the overall production of 18F in novae. Uncertainties in the parameters used to estimate these rates lead to variations in the final abundance of 18F, important for predicting potentially-observable γ-ray emission. 19F, the mirror nuclei to 19Ne, serves as one way to better understand 19Ne's structure. The region of 19F between Ex =7.0-7.3 MeV in particular remains under-examined. Level properties of 19F were studied via 15N(α,γ)19F over a range of Ec.m. = 2.8 Mev - 3.3 Mev, corresponding to Ex ~ 6.8 - 7.3. The experiment was performed using the windowless recirculating gas target system RHINOCEROS and 5U accelerator at the University of Notre Dame’s Nuclear Science Lab. The experimental data will be shown, and preliminary analysis will be discussed.
