Abstract
A simplified model of electron-hydrogen scattering is considered in which all terms involving nonzero angular momenta are neglected. Elastic scattering and excitation cross sections for the and states are calculated for this model with the use of close-coupling expansion with four different pseudostate bases. Pseudothreshold structure is observed and removed. It is found that, after removal of this structure, the results agree quite well with each other and with exact results for this model which were given previously by Poet.
