Study of 3He(n,p)3H reaction at cosmological energies with trojan horse method

In the network of reactions present in the Big Bang nucleosynthesis, the 3 He(n, p)3 H has an important role which impacts the final 7 Li abundance. The Trojan Horse Method (THM) has been applied to the 3 He(d, pt)H reaction in order to extract the astrophysical S(E)-factor of the 3 He(n, p)3 H in the Gamow energy range. The experiment will be described in the present work together with the first preliminary results.
