“…Moreover, these measurements demonstrated that utilizing theoretical estimates of the polarization transfer characteristics enables an accurate reconstruction of the incident beam polarization. As an example, such schemes for polarization diagnostics of particle and photon beams are required for exploring atomic parity violation phenomena [59,71].…”

The following errors were introduced in the production process:• In the abstract it says that at θ=90°, a degree of polarization of +0.27%±0.12% was measured. This number should be +27%±12%.• On page 5 there are three occurrences of an amplitude A. All of them should be A P instead. AbstractWe report on the first elastic hard x-ray scattering experiment where the linear polarization characteristics of both the incident and the scattered radiation were observed. Rayleigh scattering was investigated in a relativistic regime by using a high-Z target material, namely gold, and a photon energy of 175keV. Although the incident synchrotron radiation was nearly 100% linearly polarized, at a scattering angle of 90 q =  we observed a strong depolarization for the scattered photons with a degree of linear polarization of 0.27% 0.12% +  only. This finding agrees with second-order quantum electrodynamics calculations of Rayleigh scattering, when taking into account a small polarization impurity of the incident photon beam which was determined to be close to 98%. The latter value was obtained independently from the elastic scattering by analyzing photons that were Compton-scattered in the target. Moreover, our results indicate that when relying on state-of-the-art theory, Rayleigh scattering could provide a very accurate method to diagnose polarization impurities in a broad region of hard x-ray energies.

We develop ab initio relativistic QED theory for elastic electron scattering on hydrogen-like highly charged ions for impact energies where, in addition to direct (Coulomb) scattering, the process can also proceed via formation and consequent Auger decay of autoionizing states of the corresponding helium-like ions. Even so the primary goal of the theory is to treat electron scattering on highly charged ions, a comparison with experiment shows that it can also be applied for relatively light ions covering thus a very broad range of the scattering systems. Using the theory we performed calculations for elastic electron scattering on B 4+ , Ca 19+ , Fe 25+ , Kr 35+ , and Xe 53+ . The theory was also generalized for collisions of hydrogen-like highly charged ions with atoms considering the latter as a source of (quasi-) free electrons.
