摘要
利用从QED出发导出的一些相对论波动方程,计算了在J=0,L=1,S=1道正负电子散射的R矩阵。当考虑横光子的贡献时,得到了在质量1.351,1.498,1.659,1.830,2.009,2.195MeV处一些窄共振。结果同重离子碰撞实验和最近的一些Bhabha散射实验一致。
The R-matrix for the scattering of positrons on electrons is evaluated in J = 0,L = 1,S=1 channel using several relativistic wave equations derived from QEE. When transverse photon comtributions are included,obtaines very narrow resonances at mass values of 1. 351,1.498,1. 659,1. 830,2. 009,2.195 MeV results are consistent with heavy-ion and some of the recent Bhabha scattering experiments.
