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.
