MEASUREMENT OF THE ANGULAR DISTRIBUTION OF GAMMA RAYS EMITTED IN THE THREE PHOTON ANNIHILATION OF POSITRONS AND ELECTRONS
-
Abstract
We have measured the angular distribution of gamma rays emitted in three photon annihilation of positrons and electrons by the triple fast coincidence method. The experimental data are in agreement with the quantum electrodynamics (QED) prediction within the error.
