nucleon | nucleus | Fermi-Dirac statistics | 3 | 1/2 | exclusion principle | 939 MeV | The generic name for the proton and the neutron. | |
pion | Bose-Einstein statistics | 2 | -has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press | uncertainty principle | π-meson | 270 me | An unstable nuclear particle of mass intermediate between that of a proton and an electron. The pions are believed to be the particles exchanged by nucleons, resulting in the strong nuclear force; they play a role in the strong interactions analogous to that of the photons in electromagnetic interactions. |
