英文摘要The direct Coulomb explosion of N2O2+ has been investigated experimentally after double-ionization by a single extreme ultraviolet (EUV) photon with an energy of similar to 38.5 eV. From the ion-ion time-of-flight coincidence spectrum, the de-nitrogenation (N2O2+ -> N+ + NO+) and de-oxygenation (N2O2+-> O+ + N2+) photodissociation channels of N2O2+ are unequivocally identified. The measured kinetic energy release (KER) distribution of the de-nitrogenation channel presents a major peak accompanied by a shoulder structure. We find that the major peak can be attributed to the direct photodissociation of the 11Delta and 11sigma+ states, while the shoulder structure should be ascribed to the predissociation of the 11sigma and 11sigma+ states via 13pi state.
