Present work reports total cross sections for e-NO2 scattering over an extensive range of impact energy from 0.5 eV to 2000 eV, through a composite formalism. The ab initio R-matrix method is employed for calculations up to 15 eV while the spherical complex optical potential formalism is used beyond that energy. The electronic excitation cross sections are computed from ground state X(2)A(1) to seven electronically allowed excited states B-2(1), B-2(2), (2)A(2), (4)A(2), B-4(2), (4)A(1),(4)A(1) and B-4(1). The eigenphase diagrams presented here reproduces the resonances identified earlier. The structures detected at 1.33, 3 and 8.41 eV can be associated with the observed O- anion formation through dissociative electron attachment process. (C) 2013 Elsevier B.V. All rights reserved.
