Polarization observables for the scattering of two spin-(1/2 particles are organized into different classes based on the difficulty of their measurement. The large or significantly varying ones are noted. A microscopic, momentum space optical potential is used to predict all polarization observables for 250–650 MeV proton scattering from the ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ nucleus, and the observables are presented in three-dimensional plots.
