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

Summary
Big Bang nucleosynthesis (BBN) is one of the cornerstones of Big Bang cosmological model. Within BBN has been chosen a series of reactions which converts the initial protons and neutrons into helium isotopes and 7Li. Cosmological parameters and reaction rates are used as physics input of the model to calculate primordial abundaces. Among the reaction rates of great impact on the model, the 3He(n, p)3H is one complex to get, because of the neutron in the entrance channel. [1] and reference therein), difficulties arise expecially in the low-energy region, that is interesting for the BBN scenario, namely 10-900 KeV (Gamow window). For this reason, indirect methods can play an important role, as previously done for other reactions [2,3,4]. The quasi-free process, on which THM is based, is sketched in figure 1: deuteron breaks up into a neutron (participant) and a proton (spectator)
