The positron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1e, a spin of 1⁄2, and the same mass as an electron. When a low-energy positron collides with a low-energy electron, annihilation occurs, resulting in the production of two or more gamma ray photons.

Carl D. Anderson discovered the positron for which he won the Nobel Prize for Physics in 1936. The positron was the first evidence of antimatter and was discovered when Anderson allowed cosmic rays to pass through a cloud chamber and a lead plate. A magnet surrounded this apparatus, causing particles to bend in different directions based on their electric charge. The ion trail left by each positron appeared on the photographic plate with a curvature matching the mass-to-charge ratio of an electron, but in a direction that proved its charge was positive. Much mystery still surrounds anti-matter and why regular matter still existed after the big bang.
