Abstract

We have applied the Schwinger multichannel formulation [K. Takatsuka and V. McKoy, Phys. Rev. A 24, 2473 (1981)] to the elastic scattering of low-energy (1–30-eV) electrons by silane. Our results, obtained within the fixed-nuclei, static-exchange approximation, are in generally good agreement with recent differential, integral, and momentum-transfer cross-section measurements between 5 and 30 eV. At lower energies, our results reflect the known limitations of the static-exchange approximation. Near the shape resonance, the calculated differential cross section shows significant enhancement at high angles, suggesting an explanation for differences between integral cross sections determined from integrated differential data and those obtained from transmission measurements.
