Time-dependent aspects of electron degradation: Subexcitation electrons in O2-N2 mixtures

The time evolution of subexcitation electron degradation spectra in N2-O2 mixtures has been investigated by using the time-dependent Spencer-Fano equation. The calculations were performed for low-energy electrons whose energies fall below 6 eV. The present study showed that strong resonances in vibrational excitation channels in N2 and O2 greatly affect the spectrum at early times, and that the stationary spectrum is more readily achieved in energy regions with a large stopping power. The evolution of the caharacteristic features of spectra of pure N2 and O2 and their presence to various degrees in mixtures are also discussed.
