We analyze the most important spin observables representing the difference functions (P-A y ) and (P-A y )σ, along with the spin transfer coefficients D NN , D SS , and D LL in the inelastic scattering of polarized protons. We examine the excitation of the state 1 + , T = 0 (12.71 MeV) in the 12 C nucleus at the energies of projectile protons E p = 200 MeV and E p ~ 400 MeV. These spin observables are treated in the context of the exchange features of the effective interaction.

Abstrtact-Spin observables in the process ( ) are analyzed at intermediate energies in the range 100-500 MeV. Experimental and theoretical data are compared for the reaction 12 C( ) 12 C involving excitation of states 1 + , T = 0 (12.71 MeV) and 1 + , T = 1 (15.11 MeV). Two varieties of DWIA type calculations are mainly used, allowing the role of isospin effects to be distinguished.
