Calculations of elastic electron scattering by H2 for fixed nuclei

View publication

Abstract

Cross sections for elastic electron scattering by the g+1 ground state of H2 are computed at fixed internuclear distance 1.402a0, for incident energies up to 13.6 eV. Variational R-matrix calculations are supplemented by asymptotic distorted-wave calculations for higher partial waves and by a residual Born-approximation sum for the polarization potential. Polarization response is treated dynamically, using Πu1 and u+1 polarization pseudostates obtained by variational calculations. Pseudostate closed channels are included in the coupled equations integrated outside an R-matrix sphere. © 1986 The American Physical Society.
