X-ray pulse shaping by mechanical motion of resonant absorber and their applications — •Benedikt Herkommer and Jörg Evers — MPI für Kernphysik Heidelberg

For high-precision spectroscopy with highly energetic radiation as x-ray or gamma-rays it is necessary to have narrow resonances as those of Moessbauer nuclei. Despite the progress of modern x-ray sources it is still quite challenging to coherently control resonant interaction between x-rays and nuclei. In recent works it has been shown that it is possible to shape x-ray pulses in time [1] and frequency [2] domain. Theses works are based on mechanical motion of a resonant absorber.

Based on this methods this poster presents our work how different motion pattern can lead to interference of different frequencies of the the signal. This can lead to quite interesting phenomena which are discussed with regard to their use in spectroscopy applications.
