Abstract

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.
