Fast dissociation of neutral doubly excited states above the S 2p ionization threshold in H2S

A very rapid dissociation of core doubly excited states in a molecule has been observed for the first time. The channel is identified in the Auger electron spectra of H2S where the resonating structures, at higher kinetic energy than the normal Auger LVV electron lines, display non-dispersive kinetic energies relative to photon energy above the S 2p ionization limits.
