The O17(p,α)N14 reaction is of fundamental relevance in several astrophysical scenarios, such as novae, asymptotic giant branch nucleosynthesis, and γ-ray astronomy. We report on the indirect measurement of the O17(p,α)N14 reaction bare-nucleus cross section in the low-energy region. In particular, the two resonances at ERc.m.=65 keV and ERc.m.=183 keV, which dominate the reaction rate inside the Gamow window, have been observed, and the strength of the 65 keV resonance has been deduced. The reaction rate determination and the comparison with the results of the previous measurements are also discussed.
