The neutron capture of He-3 may be represented by the reaction below
[math]\displaystyle{ n + He^3 \rightarrow p + H^3 }[/math]
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
[math]\displaystyle{ p+He^3 \rightarrow p + He^3(+) + e^- }[/math]
