In order to understand primordial and stellar nucleosynthesis, we have studied H-2(d,p)H-3 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. H-2(d,p)H-3 has been studied through the Trojan Horse Method applied to the three-body reaction H-2(He-3,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 H-2(d,p)H-3 THM one, performed with a different spectator particle (see fig. 1).
