Abstract
The elastic scattering of protons and pions on polarized protons has been measured at 150 and 200 GeV/c, in a momentum transfer region still dominated by diffraction. The pp cross-section (spin-averaged) develops a dip at |t| ≅ 1.5 GeV2 which becomes more important as the energy increases. The (negative) polarization, which steadily increases from zero at t = -0.4 GeV2, reaches 10–15%; in the dip region a zero-crossing to positive values seems to take place. The π+p polarization has a similar t-dependence, while the cross-section shows no dip structure.
