Nuclei · Nuclear structure

The binding energies for the following nuclear reactions are expressed in MeV.

{}_{2}\mathrm{He}^{3} + {}_{0}\mathrm{n}^{1} \rightarrow {}_{2}\mathrm{He}^{4} + 20\ \mathrm{MeV}

{}_{2}\mathrm{He}^{4} + {}_{0}\mathrm{n}^{1} \rightarrow {}_{2}\mathrm{He}^{5} - 0.9\ \mathrm{MeV}

X_3

X_4

X_5

denote the stability of

{}_{2}\mathrm{He}^{3}

{}_{2}\mathrm{He}^{4}

and

{}_{2}\mathrm{He}^{5}

, respectively, then the correct order is:
