Polarization of Scattered Protons near 17 Mev

Experimental angular distributions of the polarization of protons elastically scattered from magnesium, calcium, copper, silver, and gold near 17 Mev are presented, and comparison with certain theoretical calculations made. Data are also given on the polarization of inelastic protons scattered from magnesium with Q=-1.37 Mev. The familiar double-scattering method was used, with carbon serving as second scatterer. It is concluded that appreciable elastic polarization may be universally expected at this energy, and that therefore some form of spin-orbit interaction is important.
