Quantum-state-resolved X-ray multiphoton ionization dynamics

XXXIV International Conference on Photonic, Electronic and Atomic Collisions
(Sapporo, Japan, July 29-August 5, 2025) [invited talk] ![[bib]](/biblio/img/bibtex.gif) [BibTeX]![[pdf]](/biblio/img/pdf.gif) [pdf]![[link]](/biblio/img/link.gif) https://www.icpeac2025.jp
I present a joint theoretical and experimental study of near-ambient pressure neon gas interacting with intense X-ray free-electron laser (XFEL) pulses. Many unexpected features are identified with quantum-state-resolved ionization-dynamics calculations in the isolated-atom limit. X-ray-driven formation of hot electron plasma and its non-equilibrium evolution dynamics are investigated in the plasma limit. Tags: XATOM,
