Neutron induced reactions play a significant role in the
nucleosynthesis of the elements in the cosmos. Its interest ranges
from the primordial processes occurred during the Big Bang
Nucleosynthesis up to the "stellar cauldrons" where neutron
capture reactions could take place via the s-process or the r-process.
In the last years, several efforts have been made to investigate the
possibility of applying the Trojan Horse Method (THM) to neutron
induced reactions mostly by using deuteron as "TH-nucleus". Here,
the main advantages of using THM will be given together with a more
focused discussion on the recent 7Be(n,alpha)4He and the 14N(n,p)14C
reactions. The former reaction was studied via the THM application to
the quasi-free 2H(7Be,aa)p reaction and it represents the extension of
the method to neutron-induced reactions in which an unstable beam is
present. The 14N(n,p)14C reaction was studied via the 2H(14N,p14C)p
experiment performed at INFN-LNS via a 50 MeV 14N beam provided by the
TANDEM accelerator. The preliminary data analysis will be also shown.
