Electron–positron annihilation occurs when an electron ( e− ) and a positron ( e+ , the electron's antiparticle) collide. At low energies, the result of...

The Large Electron–Positron Collider (LEP) was one of the largest particle accelerators ever constructed. It was built at CERN, a multi-national centre...

operates on the principle that a positron or positronium will annihilate through interaction with electrons. This annihilation releases gamma rays that can...

Richard Feynman in the spring of 1940, is the hypothesis that all electrons and positrons are actually manifestations of a single entity moving backwards...

of metals. It uses positrons which are implanted into a sample and annihilate with the electrons. In the majority of annihilation events, two gamma quanta...

The Beijing Electron–Positron Collider II (BEPC II) is a Chinese electron–positron collider, a type of particle accelerator, located in Shijingshan District...
