Resonant fragmentation of the water cation by electron impact: a Wave-Packet study
We have investigated the dissociation of a resonant state that can be formed in low energy electron scattering from H2O+. We have chosen the second triplet resonance above the (Formula presented.) (Formula presented.) state of H2O+ whose autoionization mainly produces H2O+ ((Formula presented.)). We...

| Sumario: | We have investigated the dissociation of a resonant state that can be formed in low energy electron scattering from H2O+. We have chosen the second triplet resonance above the (Formula presented.) (Formula presented.) state of H2O+ whose autoionization mainly produces H2O+ ((Formula presented.)). We have considered both dissociation of the resonant state itself, dissociative recombination (DR), or the dissociation of the H2O+ cation after autodetachment, dissociative excitation (DE). The time-evolution of a wave packet on the potential energy surfaces of the resonance and cationic states shows, for the initial conditions studied, that the probability for DR is about 38 % while the probability for DE is negligible |
