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. | ||||||||||||
charged particle | particle | uncertainty principle | A particle with non-zero charge | non-zero | electric or magnetic fields | ||||||||||
lepton | elementary particle | Fermi-Dirac statistics | 1/2 | exclusion principle | Elementary particle like the electron and neutrino that do not experience the strong nuclear force. Unlike the strongly interacting hadrons, the leptons have small masses. | ||||||||||
radioactive particle | the total energy produced when the particle decays | particle | uncertainty principle | the products produced immediately after decay | A particle which can produce harmful radioactivity directly through its decay or by interacting with other particles. | The average time in which a particle decays | |||||||||
positron | the total energy produced when the particle decays | Fermi-Dirac statistics | radioactive particle | 1/2 | uncertainty principle | antielectron | 1934 | the products produced immediately after decay | The antiparticle of the electron, discovered by Anderson in 1934. It has the same mass and spin as the electron, but opposite charge and magnetic moment. | 1 | The average time in which a particle decays | electron | Anderson | electric or magnetic fields |
