The experimental results are compared with the new theoretical results presented here. The absolute fluence of the XFEL pulse has been determined with the help of the calculations utilizing two-photon processes in the argon atom. The high charge states up to +22 observed for Xe in comparison with the calculations point to the occurrence of sequential <em>L</em>-shell multiphoton absorption and of resonance-enabled x-ray multiple ionization.</p> xenon atoms;charge states;XFEL pulse;ion TOF;arrival X position;ionization;electron laser;calculations point;mass units;multiphoton;SACLA;Xe isotopes;argon atom;Atomic Physics;Molecular Physics 2013-08-13
