The differential cross-section for the elastic neutron-proton-scattering has been measured for neutron energies between 4 and 16 GeV and | t | from 0.3 to 1.3 (GeV/ c ) 2 . The results can be fitted by exp( A + Bt ), where B increases slightly with energy indicating shrinkage. The values of B for n−p scattering are in good agreement with the corresponding data for p−p scattering.

Differential cross sections for elastic π±−p scattering have been measured at lab momenta of 8 and 12 GeV/c in a momentum-transfer region corresponding to 1.2≤−t≤6 (GeV/c)2. Also, differential cross sections near 180° were measured for 4 and 8 GeV/c pions. At momentum transfers greater than −t=2 (GeV/c)2, the π−p cross sections drop much faster with increasing angle than the corresponding p−p cross sections. Also, in the region −t≃1.3 (GeV/c)2, there is structure in the π−p angular distribution but not in the p−p angular distribution. At −t≃3 (GeV/c)2, the drop in cross section appears to stop and from then on the angular distribution is consistent with isotropy. But in the angular region 170° to 180°, the cross sections have become much larger, and sharp backward peaks are observed. Information is given on the energy and charge dependences and widths of these backward peaks.
