Vibrational excitation in e-NO2 collision at low energy (0.3–2.5 eV)

Abstract Resonant vibrational excitation by e − impact has been investigated in NO 2 . Differential cross sections for elastic and vibrational excitation present complex structures which are not simple, due to overlapping bands. Nevertheless, they indicate a long-lived resonance ( 1 A 1 ) below 1 eV and an intermediate-lifetime state above 1.1 eV ( 3 B 1 and/or 1 B 1 ).
