antineutron | electric or magnetic fields | the total energy produced when the particle decays | radioactive particle | 1/2 or 3/2 | uncertainty principle | the products produced immediately after decay | The antiparticle of a neutron. A neutron and antineutron both have the same mass and zero electric charge, but can be differentiated by their interactions: a neutron and an antineutron can annihilate into gamma rays, while two neutrons cannot. | 0 | The average time in which a particle decays | neutron | ||||
antiproton | the total energy produced when the particle decays | radioactive particle | 1/2 or 3/2 | uncertainty principle | the products produced immediately after decay | The antiparticle of a proton, identical in mass and spin but of opposite (negative) charge. | -1 | The average time in which a particle decays | proton | electric or magnetic fields | ||||
hyperon | the total energy produced when the particle decays | radioactive particle | 1/2 or 3/2 | uncertainty principle | the products produced immediately after decay | Baryons heavier than the neutron (this term is seldom used today). They have non-zero strangeness. Free hyperons are unstable and decay into end products, one of which is a proton. | 10-8 to 10-10 seconds | |||||||
nucleon | nucleus | charge multiplet | 1/2 | exclusion principle | 939 MeV | The generic name for the proton and the neutron. | -has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press |
