We report elastic integral, momentum transfer and differential cross
sections for electron scattering by N2O for energies up to 50 eV. These
results were obtained at the
static-exchange approximation with the Schwinger Multichannel Method with
Pseudopotentials [M.H.F. Bettega, L.G. Ferreira and M.A.P. Lima, Phys. Rev.
A 47, 1111 (1993)]. In general our results show good agreement with
experimental data and with other theoretical results but some discrepancies
are found. We have also found a shape resonance around 4 eV
in agreement with previous calculations using the R-matrix Method of
Sarpal et al. [J. Phys. B 29, 857 (1996)]. On the
other hand, the existence of
a
resonance at about 13 eV, clearly seen
by the Schwinger Variational Iterative Method [Michelin et al.,
J. Phys. B 29, 2115 (1996)], can not be confirmed by our
calculations. At this energy, our
cross sections show a broad
bump with no clear resonant behavior given by the eigenphase sum.
