Abstract: In this paper, the Monte Carlo method is used to calculate the energy spectrum of gamma rays emitted in the three photon annihilation of positrons and electrons. Our results are compared with the results of calculation obtained by QED and experiment. These three results mentioned above are in agreement quite well.

Key words: positrons and electrons Monte Carlo, three photon annihilation, gamma-ray energy spectrum
