We have measured neutron-proton elastic-scattering cross sections for the range 0.15 < or approx. = -t < or approx. = 3.6 (GeV/c)/sup 2/. The logarithmic slope parameter is found to be consistent with existing proton-proton parametrizations. The data also exhibit a dip in the cross section near -t approx. = 1.4 (GeV/c)/sup 2/ for incident neutron momenta above 200 GeV/c. Differences between n-p and p-p cross sections are noted in the region 0.7 < or approx. = -t < or approx. = 1.4 (GeV/c)/sup 2/.
