Low-energy electron scattering and resonant states of NO2( X 2A1)

We present new calculations of the integral elastic cross sections for electron scattering from NO2 in its ground electronic state and we also discuss the spatial shapes of its low-energy single-particle resonances. The integral cross sections are obtained as a weighted sum of the singlet and triplet scattering processes and show fair agreement with the existing experiments. The resonant states are analysed via a local model potential discussed here and the results clearly show the feasibility of interpreting known experimental features of NO2 dissociative attachment, and its similarities with the e--O3 data, in terms of the spatial shapes of the metastable single-particle scattering resonances obtained from our calculations.
