Nuclei · Nuclear structure

The energy released if hydrogen atoms are combined to form

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

is MeV.
(Take binding energies per nucleon of

{}^{2}_{1}\mathrm{H}

and

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

as 1.1 MeV and 7.2 MeV, respectively).

We corrected a printing error in the original paper

Source printed helium as a fraction “ $\frac{4}{2}$ He”; “1.1 meV”; no unit after the blank (MeV added).
