Validity test of the Trojan Horse Method applied to the7Li + p → α + α reaction via the3He break-up

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 50 keV to 7MeV. The extracted 7Li(p, α)4He quasi-free crosssection 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.
