WebBoth the annihilating electron and positron particles have a rest energy of about 0.511 million electron-volts (MeV). If their kinetic energies are relatively negligible, this total rest energy appears as the photon energy of the photons produced. Each of the photons then has an energy of about 0.511 MeV.

Web11 jun. 2024 · There is no way of evolving from an electron and a positron to photons unitarily: a measurement must be performed. And indeed, if you are certain that you started with an electron and a positron, and at the end you are certain that you have only photons, then you must have performed a measurement along the way. premier league anthony gordon
