antineutrino | electric or magnetic fields | | | antiparticle | | | | | | The antiparticle of a neutrino. | 0 | | | neutrino | | |
electron | | | element | charged particle | | | | | | Light elementary particle with a negative electrical charge. Electrons are found in shells surrounding the nuclei of atoms; their interactions with the electrons of neighboring atoms create the chemical bonds that link atoms together as molecules. | -1 | | | positron | | electric or magnetic fields |
muon | | the total energy produced when the particle decays | | | charged particle | | | | the products produced immediately after decay | Elementary particles produced when cosmic rays enter the upper atmosphere. | -1 | The average time in which a particle decays | μ | | | electric or magnetic fields |
neutrino | electric or magnetic fields | | | massless particle | | | | 0 | | A stable particle with no charge, a rest mass of zero, and a spin of 1/2, that carries away energy in the course of nuclear reactions. Its main characteristic is the weakness of its interactions with all other particles. Since the wavelengths of neutrinos at the energies at which they are normally emitted from unstable nuclei are only a few thousandths of an angstrom (compared with the wavelength of a light photon which is several thousand angstroms), they have negligible probability (10-19 that of a light photon) of interacting with matter and escape at the speed of light. Neutrinos arise only in the energy-producing regions of stars and therefore, unlike light photons, provide direct evidence of conditions in stellar cores. There are two types of neutrinos, those associated with electrons (ve) and those associated with muons (vµ). | 0 | | | antineutrino | | |
positron | | the total energy produced when the particle decays | | | radioactive particle | 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 |
tau | | the total energy produced when the particle decays | | | radioactive particle | | | | the products produced immediately after decay | | -1 | The average time in which a particle decays | τ | | | electric or magnetic fields |
