Polariton spectroscopy at the diamond K-edge via X-ray parametric down-conversion
Fridtjof Kerker, Dietrich Krebs, Xenia Brockmüller +4
It has recently been shown that x-ray parametric down-conversion (XPDC) provides access to high-energy polaritons, resulting from the hybridization of down-converted photons with e…

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…
