Abstract

The spin dependence of quasi-elastic proton-nucleus scattering is studied using Glauber’s eikonal multiple scattering theory, which is extended to include multiple knockout collisions as well as the full spin dependence of the NN amplitudes. Calculations of the cross section d2σ/dΩ dp and spin observables DNN, DLL, DSS, DSL, DLS, Ay are presented and compared to data for d2σ/dΩ dp and Ay from inclusive (p,p) experiments on C12 at Tlab=800 MeV. The main feature seen is a drop in the spin observables in the kinematic region where two nucleon knockout dominates the cross section. As an initial study of the contribution of quasi-free Δ production to the inclusive cross section, multiple scattering theory is used to normalize a plane-wave impulse approximation calculation of d2σ/dΩ dp for p+12C→p+π+12C*. .AE
