Spin dependence in intermediate energyp-nucleus scattering

We obtain closed form approximations for the spin dependent eikonal $p$-nucleus scattering amplitudes. The polarization $P$ and spin rotation function $Q$ can be written in terms of the unpolarized elastic scattering cross section and two complex parameters related to the nucleon-nucleon spin orbit strength and range. These forms agree well with the available data and illuminate the dynamical content of $P$ and $Q$.
