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

High quality analyzing power data (ΔAy≤0.05) for 800 MeV 208Pb(rvec p,p') scattering to the 0+ ground state and to the 3- 2.61 MeV collective state were obtained for θc.m.=22 degree to 37 degree, extending the range of momentum transfer out to 4.7 fm-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
