【 摘 要 】

Ionization and dissociation dynamics of N2O has been studied upon the impact of fast electrons and highly charged ions using a two-stage 3-D focusing recoil ion momentum spectrometer. The kinematics of several fragmentation channels are studied by three-dimensional momentum imaging of fragments detected in coincidence. We observe the presence of both concerted and sequential breakup channels in the decay of N2O3+molecular ion.
