Nuclear resonant scattering at X-ray free electron lasers — •Luis Yagüe Bosch and Jörg Evers — Max-Planck Institut für Kernphysik, Heidelberg, Germany

Forward scattering experiments on resonant Mössbauer nuclei using X-rays delivered by synchrotron radiation facilities are well established and can be fully described by existing quantum optical models. However, recent experiments at the EuXFEL with high spectral flux densities have revealed unexpected "anomalies" in nuclear resonant scattering (NRS) from samples containing ⁵⁷Fe Mössbauer nuclei. We explore modifications of the quantum optical models to explain the observed discrepancies. This may pave the way for deeper understanding of, and availability of new tools for Mössbauer spectroscopy.
