Probing the Linewidth of the 12.4-keV Sc Isomeric Resonance in Solids by Nuclear Forward Scattering
Peifan Liu, Miriam Gerharz, Berit Marx-Glowna +37
The Sc transition from the nuclear ground state to the 12.389-keV isomer (lifetime 0.46~s) has an ultranarrow natural linewidth $Γ_{\ind{0}}\simeq 1.4$~feV, corresponding to…

Thermoelastic response of Bragg crystals under MHz thermal loading
Peifan Liu, Kwang-Je Kim, Ryan Lindberg +1
An x-ray free-electron laser oscillator (XFELO) is a promising candidate for producing fully coherent x-rays beyond the fourth-generation light sources. An R&D XFELO experiment (AN…
