N2 - The cross sections for emission of two fluorescence photons from a pair of excited fragments in photoexcitation of H 2O have been measured as a function of the incident photon energy using the photon-photon coincidence technique. The cross section increased in the range 30-45eV, i.e. in the vicinity of the double ionization potential of H 2O. The increase of the cross section was attributed to three-body neutral dissociations of a water molecule via multiply excited states: H 2O** → H(2p) + OH** → H(2p) + H(2p) + O( 3P). Some multiply excited states of H 2O were also found in the cross section curve around 65eV.
