Multiple Ionization of Fullerenes in Intense XFEL Pulses — •Abraham Camacho Garibay, Ulf Saalmann, and Jan-Michael Rost — MPI-PKS Dresden, Germany

Ultra-intense ultra-short pulses, as provided from XFEL sources, allow the study of many-body dynamics in molecules and clusters. In the case of fullerenes, when irradiated by photons with energy well above the ionization threshold, many electrons are removed, creating a Coulombic potential in the fullerene. For the current state of intensities, we find that this process is carried on in a sequential fashion. Electron spectra differ qualitatively from low-intensity spectra as measured with synchrotrons. Emerging plateaus can be understand by means of simple model.
