The 6Li(p,α)3He reaction has been studied from Ec.m.=2.4MeV down to astrophysical energies by means of the indirect Trojan horse method applied to the 2H(6Li,α 3He) n three-body reaction performed at an incident energy of 25 MeV. Coincidence spectra measured in a kinematically complete experiment show the presence of the quasifree 6Li-p process. The excitation function for this process was extracted from the three-body reaction cross section at low neutron momentum and compared with the behavior of the free two-body reaction cross section.
