The astrophysically relevant 7Li+p{yields}{alpha}+{alpha} reaction was investigated via the THM by selecting the quasi-free contribution to the measured 3He+7Li{yields}{alpha}+{alpha}+d three-body process. This investigation is mainly aimed at testing the validity of the pole approximation in the THM against the bound structure of the Trojan-horse nucleus. The three-body experiment was performed at 33 MeV, corresponding to a 7Li-p relative energy ranging from 0.2 to 7 MeV. The quasi-free 7Li+p cross-section was compared with the free reaction cross-section as well as with indirect data from a previous THM experiment. The good agreement between data sets throughout the energy range investigated provided a very important validity test of the pole approximation for the THM.
