abstract = {We performed a time-resolved spectroscopy experixment on
the dissociation of oxygen molecules after the
interactionwith intense extreme-ultraviolet (XUV) light from
the free-electronlaser in Hamburg at Deutsches
Elektronen-Synchrotron. Using anXUV-pump/XUV-probe
transient-absorption geometry with asplit-and-delay unit, we
observe the onset of electronic transitionsin the O$^{2+}$
cation near 50 eV photon energy, marking the end ofthe
progression from a molecule to two isolated atoms. We
observetwo different time scales of 290 ± 53 and 180 ± 76
fs for theemergence of different ionic transitions,
indicating differentdissociation pathways taken by the
departing oxygen atoms.With regard to the emerging
opportunities of tuning the centralfrequencies of pump and
probe pulses and of increasing the probe−pulse bandwidth,
future pump−probe transient-absorptionexperiments are
expected to provide a detailed view of the coupled nuclear
and electronic dynamics during molecular dissociation},
