Rounding slightly, the nucleus \({ }^{3} \mathrm{He}\) has a binding energy of \(2.5 \mathrm{MeV} /\) nucleon and the nucleus \({ }^{6} \mathrm{Li}\) has a binding energy of \(5 \mathrm{MeV} /\) nucleon.

a. What is the binding energy of \({ }^{3} \mathrm{He}\) ?

b. What is the binding energy of \({ }^{6} \mathrm{Li}\) ?

c. Is it energetically possible for two \({ }^{3} \mathrm{He}\) nuclei to join or fuse together into a \({ }^{6} \mathrm{Li}\) nucleus? Explain.

d. Is it energetically possible for a \({ }^{6} \mathrm{Li}\) nucleus to split or fission into two \({ }^{3} \mathrm{He}\) nuclei? Explain.
