Analyzing powers and cross sections of inclusive polarized proton scattering on 208Pb

Inclusive polarized proton-nucleus scattering at 290 and 500 MeV was performed using a 208Pb(51 mg/cm2) target. A broad range (0-250 MeV) of excitation energy has been studied over the 4 degree-27 degree angular range. The measured analyzing power and cross section of the continuum are compared with the recent DWIA model calculations. The analyzing power and cross section of low-lying states are compared with the DWBA model calculation. The cross section in the continuum region is found to be dominated by single-step quasifree scattering. The analyzing power angular distributions of continuum peaks support RIA model predictions, and indicate the presence of relativistic medium effects
