正负电子的散射与湮没

Scatter and Annihilation of Positron梕lectron

正负电子散射在粒子物理中十分重要,其理论计算结果可直接在高能加速器上得到验证。本文探讨了正负电子散射的几种情形,并分别计算出散射矩阵元、微分截面以及总截面。

Positron-electron Scatter makes a very imports nt Part in particle physics and the therotically calculated results can be directly tested by high-energe accelerator. This article makes a research on the states of positron-electron scatter,and calculates the scattering matrix element, differential cross-section and the tatol section.
