antineutronelectric or magnetic fields  Fermi-Dirac statistics3radioactive particle1/2 or 3/2   the products produced immediately after decayThe 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.0The average time in which a particle decays neutron    
antiproton   Fermi-Dirac statistics3radioactive particle1/2 or 3/2   the products produced immediately after decayThe antiparticle of a proton, identical in mass and spin but of opposite (negative) charge.-1The average time in which a particle decays proton   electric or magnetic fields
cosmic rays  charged particle    corpuscular radiation  the products produced immediately after decayHigh-energy charged particles which stream at relativistic velocities down to Earth from space. The Sun ejects low-energy (107 - 1010 eV) cosmic rays during solar flares (those of lower energy than this are unobservable from Earth because of solar system magnetic fields). Those of intermediate energy (1010 - 1016 eV) have an isotropic distribution, and are apparently produced in the Galaxy. Possible sources of acceleration are shock waves accompanying supernovae (although cosmic rays have a higher hydrogen content than would be expected from a star that has processed material to iron), and the rotating magnetic fields of pulsars. The light elements Li, Be, and B have a higher abundance ratio in cosmic rays than in the solar system.non-zeroThe average time in which a particle decays  2 GeV (average) 85% protons, 14% alpha-particles, 1% electrons, << 1% heavy nucleielectric or magnetic fields
hyperon  radioactive particleFermi-Dirac statistics3 1/2 or 3/2   the products produced immediately after decayBaryons 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
