摘要：

We report the results of an experiment which measured np elastic scattering differential cross sections over a range in -t from 0.15 to ∼3.6 (GeV/c)2 for incident neutron momenta from 70 to 400 GeV/c. We find the logarithmic slope parameter, evaluated at -t = 0.2 (GeV/c)2, to be consistent with existing proton-proton parametrizations. The data exhibit a dip in the cross section near -t = 1.4 (GeV/c)2 for incident neutron momenta above 200 GeV/c. For neutron momenta less than 280 GeV/c, the neutron-proton cross sections are found to be higher than existing proton-proton data in the range 0.7 ≤ -t ≤ 1.3 (GeV/c)2 which is in contradiction to most Regge predictions. © 1979.
