About Positron

Positron logo

The positron or antielectron is the antiparticle or the antimatter counterpart of the electron.

The positron has an electric charge of +1 e, a spin of 1/2, and has 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
