摘要：

X-ray polarization analysis of allowed and forbidden reflections from iron pyrite, FeS2, was carried out using synchrotron radiation. Since the incident beam was sigma-polarized, the polarization of allowed reflections was also sigma. However, the polarization of the forbidden reflections; showed complex structure. From investigating the polarization and its azimuthal angle dependence, it was concluded that the reflections were caused by the ATS (Anisotropy of the Tensor of Susceptibility) scattering.
