Differential cross sections and analyzing powers of neutrons elastically scattered from ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{59}{}_{}{}^{}\mathrm{Co}$, and Pb were measured using two 183 cm long position sensitive scintillators. A beam of polarized neutrons (P=0.51, $E_{\mathrm{n}=23\mathrm{}}$ MeV) was produced by the ${}_{}{}^3{}_{}{}^{}\mathrm{H}$(d,n${)}^4$He reaction. A superconducting solenoid was used to precess the neutron spin by 180° for the determination of analyzing powers. After correcting for neutron flux attenuation and multiple scattering due to the finite size of the scatterers, the data were analyzed using a conventional optical model potential.
