Positron
Subatomic particle with positive charge
The positron or antielectron is the particle with an electric charge of +1e, a spin of 1/2 ħ (the same as the electron), and the same mass as an electron. It is the antiparticle (antimatter counterpart) of the electron. When a positron collides with an electron, annihilation occurs.

From Wikipedia
The positron or antielectron is the particle with an electric charge of +1e, a spin of 1/2 ħ (the same as the electron), and the same mass as an electron. It is the antiparticle (antimatter counterpart) of the 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. Positrons can be created 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.
