Low-energy electron scattering and resonant states of NO2((X)over-tilde (2)A(1))

We present new calculations of the integral elastic cross sections for elec tron scattering from NO2 in its ground electronic state and we also discuss the spatial shapes of its low-energy single-particle resonances. The integ ral cross sections are obtained as a weighted sum of the singlet and triple t scattering processes and show fair agreement with the existing experiment s. The resonant states are analysed via a local model potential discussed h ere and the results clearly show the feasibility of interpreting known expe rimental features of NO2 dissociative attachment, and its similarities with the e(-)-O-3 data, in terms of the spatial shapes of the metastable single -particle scattering resonances obtained from our calculations.
