'''Electron–positron annihilation''' occurs when an [[electron]] ({{SubatomicParticle|Electron}}) and a [[positron]] ({{SubatomicParticle|Positron}}, the electron's [[antiparticle]]) collide. At low energies, the result of the collision is the [[annihilation]] of the electron and positron, and the creation of energetic [[photon]]s:
