Abstract

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.
