Analyzing powers for rvec p + sup 208 Pb at large momentum transfers

High quality analyzing power data ({Delta}{ital A}{sub {ital y}}{le}0.05) for 800 MeV {sup 208}Pb({ital {rvec p}},{ital p}{prime}) scattering to the 0{sup +} ground state and to the 3{sup {minus}} 2.61 MeV collective state were obtained for {theta}{sub c.m.}=22{degree} to 37{degree}, extending the range of momentum transfer out to 4.7 fm{sup {minus}1}. Theoretical predictions for these data were obtained using analyses based on both a nonrelativistic impulse approximation approach and a relativistic impulse approximation approach. For both the elastic and inelastic analyzing powers, the relativistic impulse approximation approach provided a better description at these large momentum transfers.
