Web24 de out. de 2016 · These photons were sufficiently energetic that they could react with each other to form pairs of electrons and positrons. Likewise, positron-electron pairs annihilated each other and emitted energetic photons: γ + γ ↔ e+ + e−. An equilibrium between electrons, positrons and photons was maintained during this phase of the … The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. It has an electric charge of +1 e, a spin of 1/2 (the same as the electron), and the same mass as an electron. When a positron collides with an electron, annihilation occurs. If this collision occurs at low energies, it results … Ver mais Theory In 1928, Paul Dirac published a paper proposing that electrons can have both a positive and negative charge.
