Systematic properties of heavy nuclides reveal a fine structure in Coulomb energy that parallels variations in mass arising from n-n interactions between neutrons. These results confirm an earlier suggestion that n-n interactions in the nucleus are repulsive. Neutron emission may release up to 1.1%–2.4% of the nuclear rest mass as energy. By comparison, 0.8% of the rest mass is converted to energy...
The potential energy of a nuclide is enhanced by about 10 MeV per nucleon from the repulsion between like nucleons, and diminished by about 20 MeV per nucleon from the attraction between unlike nucleons. Nuclear stability results mostly from the interplay of these opposing forces, plus Coulomb repulsion of positive charges. Whereas fusion may be the primary mechanism by which first generation stars...
