    Abstract

    We present a comprehensive evaluation of the nuclear structure properties of Ne19 using a novel and rigorous Bayesian statistical framework. Precise characterization of Ne19 resonance parameters is critical for accurately determining reaction rates of the astrophysically significant O15(α,γ)Ne19 and F18(p,α)O15 reactions, which govern breakout from the hot CNO cycle in x-ray bursts and influence γ-ray emission in novae, respectively. By reconstructing likelihood functions from published experimental data—including asymmetric uncertainties and upper or lower limits—we derive posterior distributions for resonance energies, decay widths, and branching ratios. Our Bayesian approach systematically incorporates previously reported discrepancies among measurements, providing a statistically robust and consistent treatment of these uncertainties. The evaluated resonance parameters and associated uncertainties provide crucial input for stellar nucleosynthesis modeling, contributing to a refined understanding of explosive astrophysical phenomena.
