Abstract

We report a application of the Schwinger variational principle with plane waves as a trial basis set. Differential cross sections are obtained for e^--Ne collisions from 130 to 500 eV. Our differential cross sections are found to be in reasonable agreement with existing measurements.

Keywords: Schwinger; electron; plane waves; scattering.
