Positrons definition of Positrons by Medical dictionary

WebPositrons are the antiparticles of electrons. The major difference from electrons is their positive charge. Positrons are formed during decay of nuclides that have an excess of protons in their nucleus compared to the number of neutrons. When decaying takes place, these radionuclides emit a positron and a neutrino.

WebMar 11, 2024 · In classical physics and general chemistry, matter is any substance that has mass and takes up space by having volume. Electrons are fermions, that is, elementary particles, that is, with no substructure. A point particle is different from an elementary particle : The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. It has an electric charge of +1 e, a spin of 1/2 (the same as the electron), and the same mass as an electron. When a positron collides with an electron, annihilation occurs. If this collision occurs at low energies, it results in the production of two or more photons.
