The main process by which this happens, called the proton-proton chain, goes as follows: • Two protons come together to create deuterium, a positron, a neutrino, and energy: p + p→D+e++v+ energy • The deuterium fuses with another proton to make ³He: D + p→→ ³He + energy • Fianlly, 4He is produced by fusing two ³He nuclei together: ³He + 3 He→ 4He+p+p+ energy What is the total energy released during the creation of one 4He nucleus? Give your answer in MeV, and remember that you need to make two ³He nuclei in the process. Be sure to use at least five significant figures for your masses, but your final answer should have three or four sig figs.
