摘要：

The ion-molecule reaction N+ + O2 has been investigated experimentally using crossed beam velocity map imaging in the collision energy range from 0.15 eV to 3.0 eV. From the differential scattering cross sections, information on the branching ratios, the electronic states and vibrational levels populated in the two product channels, O 2+ + N and NO+ + O, have been obtained. These data are compared with previous results obtained using a rotatable ion source setup developed many years ago at the University of Freiburg, Germany. Furthermore, a small fraction of NO+ products populate excited electronic states as observed in chemiluminescence measurements.
