Electron Induced Emission of Nitrous Oxide in the UV-VIS Spectral Range
Keywords:nitrous oxide, emission, spectrum, electron, excitation, fluorescence
The electron impact excitation of N2O was studied using the crossed electron-molecular beams method. Optical emission spectrum initiated by 50 eV electron impact was recorded within the range 200-700 nm. Main emission bands arise from excited ion state N2O+(A2Σ) and dissociative excitation into N2+(B2Σ+u). The rotationally un-resolved excitation-emission cross sections for selected ion transitions were scaled to absolute values and their dependence on electron energy was determined. Several of them were determined for the first time.
