Nucleon–nucleon scattering

DEC 01, 1969

An atomic nucleus can be considered a set of two‐nucleon systems. What are the forces between these pairs? How do protons and neutrons differ and how are they similar? Studies during the past three decades have given some answers and indicated which new kinds of experiments are likely to be most useful.

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.
