Spin-rotation effects in elastic proton-nucleus scattering

We discuss a particular form of spin-rotation distribution in the context of proton-nuclear scattering and indicate its behaviour as a function of momentum transfer. We point out that besides effectively completing our knowledge of the nuclear scattering amplitudes the measurement of this function would furnish information both about the nuclear density distribution and about parts of the fundamental proton-nucleon spin-orbit scattering amplitudes. The latter are terms of the amplitudes which have been left undetermined by existing polarization data.
