Determination of the electric and magnetic Rayleigh scattering amplitudes — •Andrey Volotka¹, Andrey Surzhykov^2,3, and Stephan Fritzsche^1,4 — ¹Helmholtz-Institut Jena, 07743 Jena, Germany — ²Physikalisch-Technische Bundesanstalt, 38116 Braunschweig, Germany — ³Technische Universität Braunschweig, 38106 Braunschweig, Germany — ⁴Theoretisch-Physikalisches Institut, Friedrich–Schiller-Universität Jena, 07743 Jena, Germany

The Rayleigh scattering being a dominant elastic-scattering process for a wide range of photon energies extensively investigated theoretically. Relativistic calculations based on the second-order S-matrix amplitude is accepted now as a benchmark for treating the Rayleigh scattering. However, its superior to other, simpler techniques, was mainly demonstrated for the case of the angle-differential cross sections. In contrast, much less attention has been paid to the polarization studies, especially in the case of initially polarized light. Within the present studies, we investigate the possibilities for separate extraction of the electric and magnetic scattering amplitudes as well as the phase difference between them. This “complete” experiment becomes possible now with the recent advent of novel solid-state photon detectors, which provide a good energy resolution in combination with submillimeter position resolution over a large detection area.
