We report elastic integral, momentum transfer and differential cross s
ections for electron scattering by N2O for energies up to 50 eV. These
results were obtained at the static-exchange approximation with the S
chwinger 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 fo
und a (2)Pi shape resonance around 4 eV in agreement with previous cal
culations using the R-matrix Method of Sarpal et al. [J. Phys. B 29, 8
57 (1996)]. On the other hand, the existence of a (2)Sigma resonance a
t about 13 eV, clearly seen by the Schwinger Variational Iterative Met
hod [Michelin et al., J. Phys. B 29, 2115 (1996)], can not be confirme
d by our calculations. At this energy, our (2)Sigma cross sections sho
w a broad bump with no clear resonant behavior given by the eigenphase
sum.
