Abstract
Polarization properties of parametric x radiation (PXR) produced by E0=80.5MeV electrons interacting with a 13μm thick silicon crystal have been investigated. The direction and the degree of the linear polarization of PXR observed at about 20° with respect to the electron beam direction were determined by means of a novel method exploiting directional information of the photoelectric effect in a charge coupled device consisting of 6.8×6.8μm pixels. Comparison of the results with a newly derived theoretical expression exhibits very good agreement if on top of the basic interaction process underlying PXR effects decreasing the polarization are taken into account.
