| Abstract: | In this paper,we use two different methods to calculate the angular distribution of gamma rays emitted in the three photon annihilation of positrons and electrons.These two results of calculation obtained by the methods mentioned above are in agreement quite well.The joint probabbility density function of α_1,α_2,α_3 (the emission angles of photons,as shown in fig.1.1)is given out. |
