We report on experimental results on proton-deuteron elastic scattering at a centre-of-mass energy of √ s = 63 GeV . The data were obtained using the Split Field Magnet detector at the CERN Intersecting Storage Rings. The t -dependence of the elastic differential cross section, measured up to − t = 2.0 GeV 2 , is compared with the prediction of an extended Glauber theory including contributions from inelastic intermediate states. Discrepancies of up to 30% with the basic theory are observed in the interference region. The inelastic contributions are essential for the detailed description of the data both in the single- and double-scattering regions.

Proton-proton and proton-deuteron elastic scattering has been measured for incident laboratory energy from 50 to 400 GeV; minimum |t| values were, for p−p, 0.0005 (GeV/c)2, and for p−d, 0.0008 (GeV/c)2. From the differential cross sections we have determined the ratios of the real to imaginary parts of the forward scattering amplitude, ρpp and ρpd, for p−p and p−d scattering. Using a Glauber approach and a sum-of-exponentials form factor we obtain ρpn for p−n scattering.
