The final step of hydrogen "burning" in stars consists of combining two He nuclei to form a stable ,He nucleus plus two protons. How much energy is released in this final step? The mass energy of the ,He nucleus (without atomic electrons) is 2809.41 Mev, the mas energy of the ,He nucleus (without electrons) is 3728.40 Mev and the mass energy of a proton is 938.27 Mev. 3,He + ?,He → *,He +p + p
