The low-energy, bare-nucleus cross section for 15N(p,α)12C is extracted by means of the Trojan-Horse Method applied to the 2H(15N,α12C)n reaction at E beam = 60MeV. The astrophysical S-factor is compared to the direct data in the same energy region. A nice agreement shows up down to 100keV, while the low-energy behaviour of the S-factor suggests a smaller rate than is reported in the literature.
