Abstract
Results of an accurate calculation based upon the new intermediate-energy R-matrix theory are reported for electron-hydrogen-atom scattering up to 5 Ryd. Cross sections for elastic scattering and 1s-2s and 1s-2p excitation processes are presented for 1Se, 3Se, 1Po, 3Po, 1De, and 3De partial-wave symmetries. The calculation also yields phase-shifts and resonance positions and widths below the n=2 threshold which are in good agreement with previous accurate calculations.Keywords
