10.6 Exercise 4

Verify that the total number of nucleons, and total charge are conserved for each of the following fusion reactions in the proton-proton chain.

(i) $^{1} \text{H} + ^{1} \text{H} \rightarrow ^{2} \text{H} + e^{+} + v_{\text{e}}$,

(ii) $^{1} \text{H} + ^{2} \text{H} \rightarrow ^{3} \text{H} \text{e} + \gamma$, and (iii) $^{3} \text{H} \text{e} + ^{3} \text{H} \text{e} \rightarrow ^{4} \text{H} \text{e} + ^{1} \text{H} + ^{1} \text{H}$.

(List the value of each of the conserved quantities before and after each of the reactions.)
