摘要
用Monte Carlo方法计算正负电子三光子湮灭的光子能谱,并与量子电动力学(QED)理论谱及实验结果进行了比较,三种结果符合甚好。
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.
