Generation of high-fluence and high-intensity hard x-ray attosecond pulses at European XFEL
Ichiro Inoue, Ulrike Boesenberg, Rustam Rysov +41
The paper reports the generation of nanofocused hard‑x‑ray attosecond pulses at the European XFEL with peak intensities around 10^20 W/cm², verified via saturation of amplified spo…

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…
