【 摘 要 】

The influence of polarization of incident photon and non-dipole terms which arises from the multipole expansion of electron-photon interaction on properties of subsequent x-ray radiation have been studied with the MCDF method and the density matrix theory. The results show that there is a linear relationship between the degree of linear polarization of the radiative decay and ones of the incident light, which can be used for diagnosing the polarization of light source. In addition, with increasing the photon energies, the non-dipole contribution to the degree of linear polarization of radiative decay following the inner-shell photoionization will also increase.
