摘要：

Understanding the properties of F-19 levels in the range E-x=6.4-7.5 MeV is important for constraining the contributions of Ne-19 levels to the F-18(p,alpha)O-15 and F-18(p,gamma)Ne-19 thermonuclear reaction rates. We have reanalyzed N-15(alpha,alpha)N-15 data from H. Smotrich [Phys. Rev. 122, 232 (1961)] to determine properties of F-19 levels in this energy range. We find the energies and widths of broad levels to be different than previously reported and have set upper limits on the widths of postulated 3/2(+) resonances, analogs of which are important for the F-18+p rates.
