Description
Summary:•Multi-electron coincidence spectroscopy is applied to the study of electron emissions from condensed H2O molecules.•Coincidence Auger spectra are obtained for different photoelectron energies.•The energy distribution of the slow electrons ejected in the Auger decay is deduced from three-fold coincidences. Multi-electron coincidence spectroscopy using a magnetic-bottle electron spectrometer has been applied to the study of the Auger decay following O1s photoionization of condensed H2O molecules. Coincidence Auger spectra are obtained for three different photoelectron energy ranges. In addition, the energy distribution of the slow electrons ejected in the Auger decay of the O1s core hole is deduced from three-fold coincidences.
