Laser Induced Fluorescence of N 2 + ( X,v " ) Resulting From the Thermal Energy Dissociative Charge Transfer Reaction He + + N 2 O → N 2 + + O+He
Résumé
The vibrational (and rotational) energy distribution of N 2 + (X) ions produced in the He + / N 2 O charge transfer reaction at thermal energy has been measured by laser induced fluorescence using an Ion Cyclotron Resonance cell to store the ions. Vibrational levels up to V " = 5 have been observed. The relaxation processes experienced by the N 2 + (X) ions before laser detection are discussed.
