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