Rayleigh scattering of hard x-rays refers to the elastic scattering of photons on bound electrons [1]. State-of-the-art calculations in the framework of QED predict a strong dependence of the polarization characteristics of the scattered radiation on the scattering geometry [2].
We performed an experiment on the polarization transfer in Rayleigh scattering of a highly polarized hard x-ray beam on a thin gold target, extending on a previous study by Blumenhagen et al. [3]. A state-of-the-art Compton polarimeter [4] was used to precisely determine the linear polarization of the scattered radiation both within and out of the polarization plane of the incident synchrotron beam. In this contribution we will report on the setup and first results of the experiment.
