Indirect Approach To The {sup 2}H(d,p){sup 3}H Reaction Study

In order to understand primordial and stellar nucleosynthesis, we have studied 2H(d,p)3H 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 2H(d,p)H reaction has been studied through the Trojan Horse Method applied to the three‐body reaction 2H(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 2H(d,p)3H THM measurements, where a different spectator particle was employed.
