      abstract     = {We report on the use of extreme ultraviolet (XUV, 30.3 nm)
                      radiation from the Free-electron LASer in Hamburg (FLASH)
                      and visible (Vis, 405 nm) photons from an optical laser to
                      investigate the relaxation and fragmentation dynamics of
                      fluorene ions. The ultrashort laser pulses allow to resolve
                      the molecular processes occurring on the femtosecond
                      timescales. Fluorene is a prototypical small polycyclic
                      aromatic hydrocarbon (PAH). Through their infrared emission
                      signature, PAHs have been shown to be ubiquitous in the
                      universe, and they are assumed to play an important role in
                      the chemistry of the interstellar medium. Our experiments
                      track the ionization and dissociative ionization products of
                      fluorene through time-of-flight mass spectrometry and
                      velocity-map imaging. Multiple processes involved in the
                      formation of each of the fragment ions are disentangled
                      through analysis of the ion images. The relaxation lifetimes
                      of the excited fluorene monocation and dication obtained
                      through the fragment formation channels are reported to be
                      in the range of a few tens of femtoseconds to a few
                      picoseconds.},
