Abstract
Eigenphase sums and resonance positions and widths are calculated for low-energy elastic impact of electrons on NO molecules using the R-matrix method with numerically defined continuum orbitals. Calculations are performed using both the simple close-coupling and the close-coupling plus short-range polarisation models using up to six electronic states or pseudostates of the NO target. The open-shell, 2 Pi , target is found to show increased sensitivity to polarisation effects which are better represented by coupled-states calculations than by a one-state model with an optical potential. Comparison is made with the available experimental data on e-NO scattering.
