Nucleon–nucleon scattering

DETERMINATION OF THE fundamental law of force between two nucleons has occupied many physicists for the past three decades. Because the proton and electron have obvious similarities (elementarily, spin of 1/2, equal‐but opposite electric charge, Fermi statistics, antiparticles) the derivation of a nuclear “Coulomb's law” would seem to be a just reward for working in this area. As we have rather slowly and laboriously learned, however, simplicity appears to be inversely proportional to some power of the coupling constant.
