The Trojan Horse Method (THM) was applied to the 3He+ 7Li interaction in order to investigate the quasi-free 7Li(p,α)4He reaction. The three-body experiment was performed at 33 MeV corresponding to a 7Li-p relative energy ranging from 50keV to 7MeV. The extracted 7Li(p,α)4He quasi-free cross-section was compared with the behavior of direct data, as well as with the result of a previous THM investigation on the 7Li(p,α)4He reaction off the neutron in 2H. A good agreement between data sets shows up throughout the energy range investigated, providing a very important validity test of the pole approximation for the THM.
