Electron diffraction self imaging of molecular fragmentation in two step double ionization of water

Electron diffraction self imaging of molecular fragmentation in two step double ionization of water

We doubly ionize H2O by single photon absorption at 43 eV leading to H+ + OH+. A direct double ionization and a sequential process in which single ionization is followed by rapid dissociation into a proton and an autoionizing OH* are identified. We obtain information about the internuclear distance...

Zusammenfassung:We doubly ionize H2O by single photon absorption at 43 eV leading to H+ + OH+. A direct double ionization and a sequential process in which single ionization is followed by rapid dissociation into a proton and an autoionizing OH* are identified. We obtain information about the internuclear distance at which the decay of the OH* occurs from the angular distribution of the autoionization electron.
