Fusion or fission, the products need to have a higher binding energy per nucleon (proton or neutron) than the reactants. As the graph above shows, fusion only releases energy for light elements and fission only releases energy for heavy elements. The actual fusion reaction occurs when two nuclei approach within about 1.0E-15 m, so that the attraction, via the residual strong interaction between the nuclei, overcomes the electrical repulsion between the protons. Such close encounters only occur
