Conservation of Momentum in the Process of Positron Annihilation

Abstract

IT is well known that when positrons are annihilated, -rays with quantum energy of about 500 ekv. are emitted. This seems to prove that annihilation occurs with a loosely bound electron as a partner of the disappearing positron, the process involving mainly low energy positrons. Klemperer, using a coincidence method, was able to show that the annihilation is really accompanied by the simultaneous emission of two quanta. Our experiments were designed to test whether these two quanta are really emitted in opposite directions.
