Measurement of ¹⁷F (d, n) ¹⁸Ne and the impact on the ¹⁷F (p, γ) ¹⁸Ne reaction rate for astrophysics

NUCLEAR REACTIONS ²H(¹⁷F, n)¹⁸Ne, E=95.5 MeV, [secondary ¹⁷F beam from ²H(¹⁶O, n) primary reaction using RESOLUT RIB facility at the accelerator Laboratory of Florida State University]; measured reaction products, time-of-flight, E(n), I(n), E(p), I(p), Eγ, γγ-, (particle)γ-, and (¹⁷F)p-coin using RESONEUT detector system. ¹⁸Ne; deduced center-of-mass resonance-energy spectrum from invariant-mass analysis, levels, proton resonances, J, π, σ, spectroscopic factors, Γ_p, configurations, asymptotic normalization coefficients (ANCs). Coupled reaction-channel (CRC) calculation. ¹⁷F(p, γ), T₉=0.04-0.9; deduced direct-capture reaction rates for astrophysical hot CNO cycles in novas. Comparison with previous experimental results.
