Abstract
The usual treatment of the high-energy elastic scattering of protons by nuclei has been extended to include relativistic Coulomb corrections and a complex nuclear spin-orbit potential. With these additions it is possible to obtain a good fit of the experimental results on the polarization of high-energy protons scattered elastically by carbon for small scattering angles. In addition, it is possible to deduce the sign of the nuclear spin-orbit potential from the high-energy data alone. The significance of the imaginary spin-orbit potential is discussed.
