| 摘 要： | 根据密度矩阵理论，导出了受激原子态P态密度矩阵元和P态退激辐射的光子密度矩阵元的Stokes参数，它们之间存在一种非常简单直接的关系，说明在电子-光子符合散射实验中，通过测量光子的Stokes参数，就可以描述受激P态电荷云分布和散射过程的动力学。According to the density matrix theory, the density matrix of photon emitted from excited atom P state and of P state were introdued in this paper. There were a simple direct relation between the two density matrices, which shows that the electron cloud shape of excited atomic state and scattering dynamics can be described through the observable Stokes parameters of photon in electron-photon coincidence experiment.
