Multi-channel ionization dynamics of finite systems under intense Xray pulses — •Abraham Camacho Garibay, Ulf Saalmann, and Jan-Michael Rost — MPI-PKS

Xray free-electron lasers sources provide ultra-intense and ultra-short pulses, allowing the study entirely new regimes of light-matter interaction. In particular, a cluster or molecule can absorb many photons, creating a deep Coulombic potential, which depends on the instantaneous charge and instantaneous size of the (expanding) system. This potential modifies energies of photo- and Auger electrons in a characteristic manner. By means of the measurable electron spectra one may uncover the complex electron and ion dynamics in the cluster or molecule.
