Geometric structure of N 2 O q+ (q = 5, 6) studied by Ne8+ ion-induced Coulomb explosion imaging

We report the study on the complete three-body Coulomb explosion (CE) of N 2 O q + ( q = 5, 6) induced by 56-keV/u Ne 8+ ion collision with N 2 O gaseous molecule. Six CE channels for N 2 O 5+ and seven for N 2 O 6+ are identified by measuring three ionic fragments and the charge-changed projectile...

Summary:We report the study on the complete three-body Coulomb explosion (CE) of N 2 O q + ( q = 5, 6) induced by 56-keV/u Ne 8+ ion collision with N 2 O gaseous molecule. Six CE channels for N 2 O 5+ and seven for N 2 O 6+ are identified by measuring three ionic fragments and the charge-changed projectile in quadruple coincidence. Correspondingly the kinetic energy release (KER) and momentum correlation angle (MCA) distributions of three ionic fragments for each of the CE channels are also deduced. Numerical computation is presented to reconstruct the geometric structure of N 2 O q + prior to dissociation based on the measured KER and MCA. The N–N and N–O bond lengths and the N–N–O bond angles of N 2 O q + for each of the channels are determined.
