Chapter 32, Problem 32PE

Two fusion reactions mentioned in the text are $n{+}^3\text{H}{\to }^4\text{He}+\gamma$ and

$n{+}^1\text{H}{\to }^2\text{H}+\gamma$.

But reactions release energy, but the second also creates more fuel. Confirm that the energies produced in the reactions are 20.53 and 2.22 MeV, respectively. Comment on which product nuclide is most tightly bound, ⁴He or ²H.
