Abstract

In order to understand primordial and stellar nucleosynthesis, we have studied (2)H(d,p)(3)H reaction at 0,4 MeV down to astrophysical energies. Knowledge of this S-factor is interesting also to plan reactions for fusion reactors to produce energy. (2)H(d,p)(3)H has been studied through the Trojan Horse Method applied to the three-body reaction (2)H((3)He,pt)H, at a beam energy of 17 MeV. Once protons and tritons are detected in coincidence and the quasi-free events are selected, the obtained S-factor has been compared with direct reactions results. Such data are in agreement with the direct ones, and a pole invariance test has been obtained comparing the present result with another (2)H(d,p)(3)H THM one, performed with a different spectator particle (see fig. 1).
