摘要
Branching ratios and the kinetic energy released in the various fragmentation channels of energy selected N2O+ (15-20.5 eV) were investigated by the technique of threshold photoelectron-photoion coincidence. Pulsed synchrotron radiation from ACO, Orsay's storage ring, dispersed by a monochromator, was used as a photon source. Threshold electrons were energy selected on the basis of angular and temporal discrimination against energetic electrons. The energy region below 16.388 eV and the à state were investigated in detail. Below the à state, the most abundant fragment ion is O+, while above the à state NO+ dominates. Results for the B and C states are also reported. © 1980 American Institute of Physics.
