The polarization parameter in pp elastic scattering at 150 GeV/c, and in the momentum transfer interval 0.4 ⩽ −t ⩽ 3.0 GeV2, has been measured in an MWPC and scintillation counter experiment at the CERN SPS using a polarized proton target. The polarization is decreasing steadily from zero to ≈ − 10% in the range 0.4 < −t < 1.3 GeV2; for higher |t| the data suggests a change of sign. Results are also given for the differential cross section, which exhibits a small dip at −t = (1.46 ± 0.01) GeV. © 1980, All rights reserved.

Abstract
The polarization parameter in pp elastic scattering at 150 GeV/c, and in the momentum transfer interval 0.4 ⩽ −t ⩽ 3.0 GeV2, has been measured in an MWPC and scintillation counter experiment at the CERN SPS using a polarized proton target. The polarization is decreasing steadily from zero to ≈ − 10% in the range 0.4 < −t < 1.3 GeV2; for higher |t| the data suggests a change of sign. Results are also given for the differential cross section, which exhibits a small dip at −t = (1.46 ± 0.01) GeV. © 1980, All rights reserved.
