The polarization parameter in pi /sup plus or minus /p elastic scattering has been measured at several momenta in the range 2.50-5.15 GeV/c pion laboratory momentum and covering the range in t approximately from -0.2 to -2.0 (GeV/c)/sup 2/. The data show positive polarization for pi /su p +/ p scattering, having a dip near t =- 0.6 (GeV/c)/sup 2/ and becoming relatively large at greater values of - t. The results for pi /sup +/ and pi /su p -/ scattering are approximately equal in magnitude but of opposite sign. The data have been analyzed to separate the components, which are symmetric and antisymmetric with respect to pion charge, and to show both the t and s dependence of each part. (auth)
