Enhanced One-Color-Two-Photon Resonant Ionization in Highly Charged Ions by Fine-Structure Effects
Moto Togawa, Chunhai Lyu, Chintan Shah +25
Ultraintense pulses from X-ray free-electron lasers can drive, within femtoseconds, multiple processes in the inner shells of atoms and molecules in all phases of matter. The ensui…

Laboratory Measurements of Ca XIX Dielectronic Recombination Satellites
Filipe Grilo, Marc Botz, Chintan Shah +3
We report measurements of the K emission from the astrophysically very abundant Ca XIX (He-like ion) and its satellite lines resonantly excited by dielectronic recombination (DR…

Comprehensive Laboratory Benchmark of K-shell Dielectronic Satellites of Fe XXV-XXI Ions
Chintan Shah, Pedro Amaro, Filipe Grilo +7
We report on comprehensive laboratory studies of the K-shell dielectronic recombination (DR) resonances of Fe XXV - XXI ions that prominently contribute to the hard X-ray spectrum…
