Double differential cross sections and analyzing powers over the quasielastic region have been measured using the (p→,n) reaction on ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ and ${}_{}{}^{\mathrm{nat}}{}_{}{}^{}\mathrm{Pb}$. The data were obtained at proton energies of 495 and 795 MeV and cover momentum transfers from 1.0–2.1 ${\mathrm{fm}}^{\mathrm{-}1}$ at 495 MeV data and from 0.0–3.5 ${\mathrm{fm}}^{\mathrm{-}1}$ at 795 MeV. The cross section data are compared to results from a nonrelativistic reaction model that includes contributions from two-step scattering. The analyzing power measurements are compared to a recent relativistic plane-waves model.
