Indirect measurement of the 15N(p, α)12C reaction cross section through the Trojan-Horse Method

Abstract

The low-energy, bare-nucleus cross section for 15 N(p, α) 12 C is extracted by means of the Trojan-Horse Method applied to the 2 H( 15 N, α 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.
