Chapter 31, Problem 69PE

²H is a loosely hound isotope of hydrogen. Called deuterium or heavy hydrogen, it is stable but relatively rare−it is 0.015% of natural hydrogen. Note that deuterium has Z = N, which should tend to make it more tightly bound, but both are odd numbers. Calculate BE/A, the binding energy per nucleon, for ²H and compare it with the approximate value obtained from line graph in Figure 31.27.
