(virtual, July 20-23, 2021)
Results on photon-energy-dependent multiphoton ionisation of xenon using intense soft X-ray FEL pulses at the SQS instrument at the European XFEL will be presented. Ion yields for charge states up to Xe41+ were recorded over a wide photon-energy range (700-1800 eV) in small steps while maintaining high pulse energy (several mJ). Thereby, we observed distinct ion-yield variations in the charge-state distributions as a function of the photon energy due to inner-atomic resonances.
