New analysis of p + ¹⁹F reactions at low energies and the spectroscopy of natural-parity states in ²⁰Ne

NUCLEAR REACTIONS ¹⁹F(p, α₀), E=0.18-3.35, 4.3-12.3, 2.12-2.62, 2.72-3.13 MeV; ¹⁹F(p, α), E=0.6-1.05, 0.79-0.87, 1.1-1.38, 1.55-2.38, 2.72-2.8, 2.06-2.18 MeV; ¹⁹F(p, p₀), E=0.66-1.8 MeV; analyzed experimental data for integrated cross sections, differential cross sections, angular distributions using R-matrix fits for α₀, α_π and p₀ channels. ²⁰Ne; deduced levels, resonances, J, π, S factors, widths of natural- and unnatural-parity states above S(p); calculated astrophysical reaction rates for T₉=0.005-5.
