Resumen
Elastic differential, integral, and momentum-transfer cross sections are reported for electron scattering by GeH4 at impact energies ranging from 0.2 to 100 eV. The Schwinger iterative variational method in the fixed-nuclei, static-exchange plus correlation-polarization approximation is used to calculate the scattering amplitudes. Large-angular-momentum contributions from the correlation-polarization potential to the scattering amplitude are taken into account via a closed formula for higher incident energies. We have observed a T-2 shape resonance in the ICSs and MTCSs at around 3.0 eV and we have predicted a Ramsauer-Townsend minimum at around 0.6 eV. Our calculated cross sections are compared with recent experimental data and other theoretical results. [S1050-2947(99)00102-X]. 59 2 1208 1215
