Abstract / Description:We have investigated multiphoton multiple ionization dynamics of xenon atoms using a new x−ray free−electron laser facility, SPring−8 Angstrom Compact free electron LAser (SACLA) in Japan, and identified that Xe(n+) with n up to 26 is produced at a photon energy of 5.5 keV. The observed high charge states (n≥24) are produced via five−photon absorption, evidencing the occurrence of multiphoton absorption involving deep inner shells. A newly developed theoretical model, which shows good agreement with the experiment, elucidates the complex pathways of sequential electronic decay cascades accessible in heavy atoms. The present study of heavy−atom ionization dynamics in high−intensity hard−x−ray pulses makes a step forward towards molecular structure determination with x−ray free−electron lasers
