Abstract: | Emission spectra between 185 and 600 nm have been investigated following near-thermal charge exchange between He+ and N2O and ≤ 100 eV electron impact on N2O. The charge exchange produces N2O+Ã→X?and N2+ B → X emission, but the two band systems account for at most 5% of all charge transfer products. These results and literature data on Ar+/N2O are discussed in the light of Franck—Condon and energy resonance criteria as applied to low-energy charge exchange. The electron-impact experiments revealed a weak (≈ 10?3) long-lived (≈ 50 × 10?6 s) component in the N2O+Ã→X?emission. |
