A dissociation channel mediated by the vibrational motion in the excited states of molecules of water was observed. H2+ formation via the core excitation of H 2O was observed as a function of vibrational quantum numbers. Results showed that excitation of water caused the bending motion mixed with the symmetrical stretching motion. H2+ fortmation along the final states increased linearly with the vibrational energy stored in the core-excited state. Ab inito calculations indicated a key role of nuclear motion before Auger decay in hydrogen ion formation.
