AB  - An accurate description of the interaction of intense hard X-ray pulses with heavy atoms,which is crucial for many applications of free-electron lasers, represents a hitherto unresolvedchallenge for theory because of the enormous number of electronic configurations andrelativistic effects, which need to be taken into account. Here we report results on multipleionization of xenon atoms by ultra-intense (about 1019W/cm2) femtosecond X-ray pulses atphoton energies from 5.5 to 8.3 keV and present a theoretical model capable of reproducingthe experimental data in the entire energy range. Our analysis shows that the interplay ofresonant and relativistic effects results in strongly structured charge state distributions,which reflect resonant positions of relativistically shifted electronic levels of highly chargedions created during the X-ray pulse. The theoretical approach described here provides a basisfor accurate modeling of radiation damage in hard X-ray imaging experiments on targets withhigh-Zconstituents.
