The 19F(p,α0)16O and 19F(p,απ)16O reactions can be fruitfully exploited to probe natural parity states above the proton emission threshold in the compound 20Ne nucleus. However, despite the relatively large number of data sets published in the literature, it is still not possible to draw a fully unambiguous picture of the spectroscopy of 20Ne, especially close to the proton emission threshold. To contribute to clarify these aspects, we have collected and reviewed all existing data sets of the 19F(p,α0)16O and 19F(p,απ)16O reactions to perform, for the first time, a comprehensive R-matrix fit including both reactions in the bombarding energy range Ep = 0:2–10 MeV. Our analysis clarifies several ambiguities present in the literature and affecting the spectroscopy of 20Ne and clearly demonstrates the importance of the 19F(p,απ) reaction to better constraint the spectroscopy parameters of the fit.
