We report on the indirect measurement of the O-17(p,alpha)N-14 reaction bare-nucleus cross section in the low-energy region. In particular, the two resonances at E-R(c.m.) = 65 keV and E-R(c.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.
