Differential cross sections and polarization analyzing powers for proton-deuteron elastic scattering have been measured at 800 MeV incident proton kinetic energy over the range of center-of-mass angles from 14.1° to 153.6°. The differential cross sections are described by the Glauber theory of impulse approximation at forward angles ($-t<\mathrm{}0.5\mathrm{}$) and exhibit the exponential dependence on ${cos\theta }_{\mathrm{c}.\mathrm{m}.\mathrm{}}$ typical for these energies at backward angles (${cos\theta }_{\mathrm{c}.\mathrm{m}.\mathrm{}}<-0.5\mathrm{}$). The analyzing power shows considerable structure with strong positive peaks at forward and backward angles and a sharp dip at $t=-0.4\mathrm{}$ typical at intermediate energies. There is no evidence for correspondence of the angular dependence of the analyzing power with that for the $\mathrm{pp}\to d{\pi }^{+}$ reaction. At large momentum transfer the data favor calculations based on multiple scattering with a modified deuteron form factor rather than $N^{*}$ exchange.
