Dynamical Phase Control in Resonant Nuclear Scattering — •Patrick Reiser, Andreas Kaldun, Christoph H. Keitel, Thomas Pfeifer, and Jörg Evers — Max-Planck-Institut für Kernphysik, Heidelberg

In spectroscopy, the observed signatures arise from interference between the incident probing light and the light scattered by the sample. By imprinting a relative phase between incident and scattered light, a modification of spectral line shapes can be achieved [1,2]. Motivated by this, our aim is to establish dynamical phase control at x-ray energies. We propose a setup using resonant nuclear forward scattering of synchrotron radiation on ⁵⁷Fe Mössbauer nuclei. The phase shifts are mechanically mediated via piezoelectric film elements. Our theoretical calculations suggest that this setup provides access to a number of promising applications in nuclear quantum optics. Additionally, first results from a Mössbauer test experiment will be shown.
