We present differential cross-sections for pp elastic scattering at eight laboratory momenta from 1.50 to 2.06 GeV/c. The data are analysed using an 8-parameter optical modelà la Frahn and Venter. However, the best representation of the differential cross-sections is obtained by combining the glory model with a parametrization of the scattering amplitude in terms of coherent exponentials. Both representations show the dominance of the partial wave with orbital angular momentum equal to four.

The experimental data on d-d collisions at 4.3, 6.3 and 8.9 GeV/ c , exhibiting the two-peak structure in the high-momentum parts of the secondary deuteron spectra at momentum transfers | t | ≈ 0.4–0.8 (GeV/ c ) 2 , are presented. An analysis of the results in terms of the multiple nucleon-nucleon scattering model is given. Some conclusions about the mechanism of the elastic and quasielastic d-d scattering at the above-mentioned momentum transfers are made.

The spectrum and yield of protons produced by 60-, 100-, and 200-MeV π+ and π− beams on targets of He4, C12, Ni62, and Ta181 have been measured at 45° and 90°. A distinct high-energy component is seen in the protons from He4, which is consistent with a two-body absorption mechanism. Its cross section at 220 MeV is somewhat larger than calculated from the π+ + D process. Possible evidence is also seen for multinucleon absorption modes. The data on heavier nuclei are consistent with earlier experiments.

Differential cross sections have been measured for the interactions p p → π − π + and p p → K − K + over a centre of mass angular range −0.95 ⩽ cos θ ∗ ⩽ 0.95 at 20 incident momenta between 0.79 and 2.43 GeV/ c . A magnetic spectrometer with wire spark chambers was used. Typically 2000 π − π + and 300 K − K + events were obtained at each momentum. Results are compared with those from related experiments.

The differential cross section for the reaction π − p→n π ° has been measured with high statistics at six incident beam momenta between 1.0 and 2.4 GeV/ c . The results are compared with predictions of recent phase shift analyses and forward dispersion relations.
