Time-resolved core-level photoelectron spectroscopy — •Christian Oberer, Martin Michelswirth, Hatem Dachraoui, Jochen Vieker, Tobias Milde, Norbert Müller, and Ulrich Heinzmann — Molecular and Surface Physics, University of Bielefeld

An experimental setup based on a combination of few femtosecond EUV pulses from high-harmonic generation, with time-of-flight (TOF) analysis of the emitted photoelectrons. A selection of the 61th harmonic 95 eV from the harmonic spectrum of the light source is achieved with a multilayer Mo/Si double mirror monochromator. Our data present a clear demonstration of the potential of femtosecond time-resolved core-level photoelectron spectroscopy to directly study ultrafast dynamical processes at surfaces and in condensed matter systems.
