The time evolution of subexcitation electron degradation spectra in N{sub 2-}O{sub 2} 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 N{sub 2} and O{sub 2} greatly affect the spectrum at early times, and that the stationary spectrum (time {r arrow}{infinity}) is more readily achieved in energy regions with a large stopping power. The evolution of the characteristic features of spectra of pure N{sub 2} and O{sub 2} and their presence to various degrees in mixtures are also discussed.
