 Electron–positron annihilation

The annihilation of an electron with a Positron, producing other particles; a common final state consists of two photons.

Electron-positron annihilation is a fundamental process in particle physics that occurs when an electron (a negatively charged subatomic particle) encounters its antiparticle, the positron (which has the same mass as the electron but a positive charge). When they meet, they can annihilate each other, resulting in the conversion of their mass into energy, typically in the form of photons (gamma rays).
