Positron Electron boom

  1. Dec 5, 2013 #1
    so if a positron and an electron boom each other and create 2 photons, how do I tell the total energy of the two photons? does a positron have anti mass equal to the magnitude of the electron? so the two photons total energy would be 2(m_e)*c^2

    Positrons and electrons have equal mass. Total energy of the photons would be equal to the sum of the two particles' masses plus the kinetic energy they had at the time of the annihilation event.
