10.6 Exercise 6

Show that the total energy released in the proton-proton chain is 26.7 MeV, considering the overall effect in $^{1} \text{H} + ^{1} \text{H} \rightarrow ^{2} \text{H} + e^{+} + v_{\text{e}}$, $^{1} \text{H} + ^{2} \text{H} \rightarrow ^{3} \text{H} \text{e} + \gamma$, and $^{3} \text{H} \text{e} + ^{3} \text{H} \text{e} \rightarrow ^{4} \text{H} \text{e} + ^{1} \text{H} + ^{1} \text{H}$. Be sure to include the annihilation energy.
