α particle space distribution from fusion reactions in Boron irradiated by mono-energetic protons

Abstract

This work presents results regarding the p + 11B → 3α + 8.7MeV aneutronic fusion reaction. We obtained such results by directing a 0.675 MeV proton beam from a Tandetron accelerator to a solid Boron sample, varying the incidence angle. Three different detectors were used to reveal the alpha particles emitted during the experiments. The evidence obtained leads us to propose an innovative scheme to investigate the yield of the aneutronic reaction when the proton beam is directed against a 11B laser induced plasma.
