Study of Pseudostate Expansion in a Simplified Model of Elastic Electron Scattering from Helium
Abstract: In this paper, we present a simplified model of
electron-helium scattering in which all terms involving nonzero orbital angular momentum are
neglected. Elastic scattering cross sections are calculated for this model by
using the close-coupling expansion with a non-orthogonal Laguerre-L2 basis function. It is found that the results
are in good agreement with experiments and with the other theoretical results.
