摘要
作者对轫致辐射的散射矩阵S(T,- T) 进行了计算,这里2 T指轫致辐射中的相互作用时间。计算结果发现:运用S(T,- T) 计算散射截面时不再有红外发散。
In this paper we calculate the scattering matrix S(T,-T) for the bremsstrahlung process, here 2 T is the effective interaction time of the bremsstrahlung process. We find an interesting conclusion: there is no infrared divergence when the cross section is calculated with S(T,-T) .
