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 deduced and compared to the direct data in the same energy region. A fair agreement with direct data down to 80 keV is found if energy resolution effects are taken into account.

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 deduced and compared to the direct data in the same energy region. A fair agreement with direct data down to 80 keV is found if energy resolution effects are taken into account.File in questo prodotto:
