abstract
The vibrational structure of the O1s[-1]2b2 core-excited state of H2O is observed and ascribed to the mixture of symmetric stretching and bending motions with a1 symmetry. The formation of H2+ is found to increase linearly with an increase in energy stored in the nuclear motion of the O1s[-1]2b2 state, demonstrating that this dissociation channel is mediated by the nuclear motion in the core-excited state. The reaction pathway to the H2+ formation along the Auger final state of H2O+, mediated by the nuclear motion before the Auger decay, is discussed with the help of ab initio potential surfaces of the Auger final states.
