Neutron - Proton Elastic Scattering from 70-GeV/c to 400-GeV/c

The authors have measured neutron-proton elastic scattering cross sections for four-momentum transfers .17 {le} -t {le} 3.5(GeV/c){sup 2}. The logarithmic slope parameter is found to be consistent with existing proton-proton parameterizations. 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 .7 {le} -t {le} 1.4(GeV/c){sup 2}
