19F(p,α) reactions are important both in nuclear astrophysical field and for the study of the inner structure and the cluster behaviour in light nuclei. The available cross section data on such reaction, although being in reasonable agreement over a wide energy range, still show some discrepancies for both α0 and απ channels. In this work we discuss the preliminary results of a new experiment aimed to solve the disagreement around 1.6 MeV for the 19F(p,α0) absolute cross section. The excellent resolution of the detection device allowed us also to resolve the απ peak in the spectra obtained in the 1.0-1.5 MeV beam energy range, where very few data where previously reported in the literature.
