| 英文摘要 | The prompt and delayed dissociations of N2O2+ -> N+ + NO+ induced by electron capture collisions of 56-keV/u Ne4+ and Ne8+ ions are studied by measuring ion-pair fragments and charge-changed projectiles in triple coincidence. For the prompt dissociation, the kinetic energy release (KER) distributions are obtained and indicate this process is mainly attributed to the decay of the low-lying 1 (3)Sigma(-) state N2O2+ into N+(P-3) + NO+((1)Sigma(+)). For the delayed dissociation, since it is of difficulty to directly retrieve three-dimensional momentum vectors of ionic fragments for all the events from N2O2+ dissociation in flight, an alternative way is proposed to only catch and analyze the events from which the N2O2+ breakup direction is perpendicular to the time-of-flight axis. The KER distributions for these events are obtained and the metastable states of N2O2+ are confirmed to be 1 (3)Pi and 2 (3)Pi. The survival time spectra for the metastable N2O2+ are also extracted and the mean lifetimes for the 1 (3)Pi and 2 (3)Pi conjoin, as well as the lifetimes for the identified individual metastable state, are deduced both in Ne8+ and Ne4+ collision experiments. |
