How does a positron differ from an electron
WebElectron–positron annihilation occurs when an electron ( e− ) and a positron ( e+ , the electron's antiparticle) collide. At low energies, the result of the collision is the annihilation of the electron and positron, and the creation of energetic photons : e− + e+ → γ + γ WebMay 7, 2014 · 1 Answer. Positron emission gives a new nucleus with the same mass number but an atomic number that is one less than the old one. Electron emission gives an atomic number that is one greater. Both positrons and electrons are β particles. A positron is the antimatter counterpart of an electron (β⁻). A positron is a positive electron (β⁺).

WebPositron emission is mediated by the weak force. The positron is a type of beta particle (β + ), the other beta particle being the electron (β −) emitted from the β − decay of a nucleus. … 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 … See more Theory In 1928, Paul Dirac published a paper proposing that electrons can have both a positive and negative charge.
