The polarization of the recoil proton has been measured in both high-energy elastic and inclusive proton-proton scattering at the internal-target area of Fermi National Accelerator Laboratory. The polarization in elastic scattering was measured at a number of center-of-mass energies up to ..sqrt..s-bar=19.7 GeV. Indications of negative polarization were seen at the higher center-of-mass energies for t values of -0.6, -0.8, and -1.0 (GeV/c)/sup 2/. In the inclusive process p+p..-->..p/sub arrow-up/+X the polarization was found to be independent of beam energy from 100 to 400 GeV for x/sub F/ values of -0.7, -0.8, -0.9. The polarization at P/sub T/=1.0 GeV/c, x/sub F/=-0.7 and x/sub F/=-0.8 was less than 2.5%. This is significantly lower than the corresponding measurements reported for ..lambda../sup 0/ inclusive polarization.
