Elastic electron scattering by silane in the low-energy range

Elastic differential, integral and momentum-transfer cross sections are reported for electron scattering by SiH4 at impact energies ranging from 0.1 to 40 eV. A new code based on the Schwinger iterative variational method in the fixed-nuclei, static-exchange plus correlation-polarization approximation is used to calculate the scattering amplitudes. Our calculated cross sections are in general good agreement with the available experimental data as well as with some recent theoretical results. The new code is also able to reproduce the Ramsauer-Townsend minimum at 0.2 eV and the resonance at 3 eV. The good results of the present application reinforce the reliability of our method.
