The neutron capture of He-3 may be represented by the reaction below
About 764 keV of energy is liberated in this nuclear reaction and distributed between the final products according to their masses. Because the proton is abotu a factor of 3 lighter that T ritium (H^3) , it will have more kinetic energy by about a factor of 3 (about 573 keV). This liberated proton can ionize other He-3 atoms via the reaction
