A 15-state [ital R]-matrix calculation has been carried out at 685 energies ranging from 1--17 eV to depict the resonant profiles for the elastic differential cross sections and the angular distribution of the spin asymmetry [ital A][sub 1[ital s]-1[ital s]]([theta],[ital k][sup 2]) in the elastic scattering of spin-polarized electrons by spin-polarized hydrogen atoms at angles of 30[degree], 55[degree], 70[degree], and 90[degree]. The calculations are compared with experiments.
