The experimental study of the O-17(n,alpha)C-14 reaction has been performed in the energy range 0-350 k.eV. This reaction could play an important role in explaining heavy elements (s-process) nucleosynthesis in various astrophysical scenario. To overcome the practical problems arising from the neutrons production, a new application of the Trojan Horse Method has been recently suggested. In more details, the 170(n,a)14C reaction has been studied using the quasi-free H-2(O-17,alpha C-14)H-1 reaction, induced at an energy of 43.5 MeV. The measurement allows one to investigate the l=3, 75 keV resonance (E*=8.125 MeV , J(pi)=5(-)), absent in the available direct measurements because of centrifugal suppression effects.
