Available in PDF, EPUB and Kindle. Book excerpt: Using a polarized proton target, we have measured the polarization parameter P([theta]) in pion-proton scattering for both positive and negative pions. Because there seems to be a great deal of current interest in the analysis of pion-proton scattering we wish to present these experimental results at this time even though we have not yet completed their analysis. The measurement consisted of scattering pions from polarized target protons and observing the asymmetry in scattered intensity, I([theta]), as the target protons spin directions were reversed. The intensity for scattering from a target of polarization P{sub T} is I([theta]){sub pol.} = I([theta]){sub unpol.} (1 + P([theta])P{sub T}), where the parameter P([theta]) is the same as the recoil proton polarization in scattering pions from unpolarized protons under the assumption that parity is conserved in the process.
