Upon ionization of ground state O2 molecules in a short XUV pulse, we observe a time-dependent vibrational wave packet in the potential of the binding O+ 2 (a4?u) state. Our pump-probe delay dependent kinetic-energy-release (KER) spectra are in qualitative agreement with the results of coupled-channel simulations that are based on calculated Born-Oppenheimer potential-energy curves (PECs). Using a Morse potential adjusted to the experimental data most features of the experimental spectra are reproduced quantitatively. © Published under licence by IOP Publishing Ltd.
