| Abstract: | In this paper, the Monte Carlo Method of sampling from the cons-trained condition is presented in detail. The angular distribution of gamma rays emitted in three photon annihilation of positions and electrons is calculated on the basis of the method described above. Our numerical results are in agreement with the Quantum Electrodynamics (QED) prediction with in the error. |
