antiparticle  particle    uncertainty principle Particles with identical mass and spin as those of ordinary matter, but with opposite charge. Antimatter has been produced experimentally, but little of it is found in nature. Why this should be so is one of the questions that must be answered by any adequate theory of the early universe.   
baryon  fermionFermi-Dirac statistics3 1/2 or 3/2exclusion principle Heavy subatomic particle composed of 3 quarks.   
neutral particleelectric or magnetic fields particle    uncertainty principle A particle with zero charge0  
radioactive particle the total energy produced when the particle decaysparticle    uncertainty principlethe products produced immediately after decayA particle which can produce harmful radioactivity directly through its decay or by interacting with other particles. The average time in which a particle decays 
antineutronelectric or magnetic fieldsthe total energy produced when the particle decays Fermi-Dirac statistics3radioactive particle1/2 or 3/2uncertainty principlethe 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 decaysneutron
