Abstract

We report an application of the Schwinger variational principle with plane waves as a trial basis set. Differential cross sections are obtained for electron-SiH₄ collisions from 7.5-40 eV. Our differential cross sections are found to be in reasonable agreement with experimental data.

Keywords: Electron scattering; Schwinger variational principle.
