Interferometric characterization of the relative phase between two X-ray free-electron laser pulses using long-lived Mössbauer resonances
Lukas Wolff, Jörg Evers
Coherence-based spectroscopy methods are powerful tools to explore structure and dynamics of matter. However, towards higher photon energies, the generation of sequences of pulses…
Cumulant expansion approach to the decay dynamics of interacting Mössbauer nuclei after strong impulsive excitation
Miriam Gerharz, Jörg Evers
Recent progress in accelerator-based x-ray sources brings higher excitation of ensembles of Mössbauer nuclei closer to experimental feasibility. Yet, a theoretical modeling of the…
Single-shot sorting of Mössbauer time-domain data at X-ray free-electron lasers
Miriam Gerharz, Willi Hippler, Berit Marx-Glowna +28
Mössbauer spectroscopy is widely used to study structure and dynamics of matter with remarkably high energy resolution, provided by the narrow nuclear resonance line widths. Howev…
Dark-fringe interferometer with dynamic phase control for Mössbauer science
Miriam Gerharz, Dominik Lentrodt, Lars Bocklage +10
Interference is a powerful tool for measuring and control. In Mössbauer science, interference effects are essential to most applications, due to the coherent scattering nature. Ho…
Probing the Linewidth of the 12.4-keV Solid-State Sc Isomeric Resonance
Peifan Liu, Miriam Gerharz, Berit Marx-Glowna +37
The Sc nuclear transition from the ground to the isomeric state at 12.389~keV, with a lifetime of 0.46~s, exhibits an extraordinarily narrow natural width of 1.4~feV and a q…
Excitation of narrow x-ray transitions in thin-film cavities by focused pulses
Dominik Lentrodt, Christoph H. Keitel, Jörg Evers
A method to compute the excitation of narrow transitions at hard x-ray energies by short focused x-ray pulses is developed. In particular, the effect of thin-film cavities on the p…
