The positron has an electric charge of + 1 e, a spin of 1 / 2 (same as electron), and has 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 gamma ray photons (see electron--positron annihilation). </P> <P> Positrons may be generated by positron emission radioactive decay (through weak interactions), or by pair production from a sufficiently energetic photon which is interacting with an atom in a material . </P>

A positron is the antiparticle of the electron
