Effects of long-range correlations on high-energy elastic and inelastic proton--nucleus scattering are investigated using the eikonal approximation. We treat multiple scattering of the proton in a coupled channel formalism where virtual excitations and de-excitations of the nucleus are allowed during the scattering process. This is completely equivalent to considering many-body correlations to any order. We also study effects of spin and isospin dependence of the nucleon--nucleon interaction in elastic and inelastic p + nucleus scattering. We propose to use inelastic scattering to known nuclear states as an analyzer of the different components of the nucleon--nucleon interaction. The strong p + nucleus interaction is treated in close analogy to electromagnetic and weak interactions where similar nuclear matrix elements occur. We calculate cross sections and polarizations using all information available from nucleon-- nucleon and electron--nucleus scattering. Numerical results are compared with experimental data for elastic scattering of 1 GeV protons on $sup 12$C and electric excitations of the I/sup $pi$/T (E/MeV) =2$sup +$0(4.43), 0$sup +$0'(7.66) and 3$sup -$0(9.64) states in $sup 12$C. We predict the differential cross section and polarization for a magnetic transition to the 1$sup +$1(15.11) state in $sup 12$C. (AIP)
