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.

The (2)H(d,p)(3)H reaction has been studied through the Trojan Horse Method applied to the three-body reaction (2)H((3)He,pt)H, at beam energy of 17 MeV. Once selection of protons and tritons detected in coincidence and the selection of quasi-free events, the obtained S-factor is compared with direct measurements. Such data are in agreement with the direct ones and a pole invariance test has been obtained comparing the present results with another (2)H(d,p)(3)H THM measurements, where a different spectator particle was employed.

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 its S-factor is interesting also to plan reactions for fusion reactors to produce energy. The (2)H(d,p)(3)H reaction has been studied through the Trojan Horse Method applied to the three-body reaction (2)H((3)He,pt)H, at beam energy of 17 MeV. Once selection of protons and tritons detected in coincidence and the selection of quasi-free events, the obtained S-factor is compared with direct measurements. Such data are in agreement with the direct ones and a pole invariance test has been obtained comparing the present results with another (2)H(d,p)(3)H THM measurements, where a different spectator particle was employed.
