Trojan Horse as indirect technique in nuclear astrophysics

ORAL

Abstract

The Trojan Horse method (THM) is a powerful indirect technique which allows one to determine the astrophysical factor for rearrangement reactions with bare nuclei (i. e. without electron screening) down to zero energy. We will present the latest results for the astrophysical factor for the resonant reaction $^{15}$N(p,$\alpha$)$^{12}$C determined using the Trojan Horse reaction $^2$H($^{15}$N,$\alpha$$^{12}$C)n at E$_{beam}=60$ MeV. The measurements have been done at Texas A\&M University in collaboration Catania National Lab- Texas A\&M University. The astrophysical $S$ factor is compared with the direct data in the same energy region. A fair agreement is found down to $80$ keV, while the low-energy behaviour of the $S$ factor suggests a smaller rate than reported in literature.
