Resorting to resonant Auger spectroscopy mitigates the energy resolution limit of time-resolved X-ray photoelectron spectroscopy, but reconstructing the full nuclear wavepacket evolution from it is an open challenge. The authors retrieve the full information of a nuclear wavepacket from time-resolved resonant Auger spectroscopy measurements.
