We have performed calculations of the spin asymmetry in elastic scattering of electrons by hydrogen atoms using an optical potential appraoch. An 18-state basis set is employed. The scattering calculations are carried out explicitly for the channels corresponding to the lowest six states. The effects of other channels are included via a second-order optical potential. The present values of the asymmetry at 90/sup 0/ are in agreement with the recent experimental values of Fletcher et al. and resolve the discrepancy between theory and experiment which they reported in the intermediate-energy region.
