Neutron-proton charge-exchange scattering from 22 to 65 GeV/c

Abstract The differential cross sections for neutron-proton elastic charge-exchange scattering have been measured with a two-arm technique for incident neutron momenta between 22 and 65 GeV/c and for values of the momentum transfer squared between 0.002 and 0.8 (GeV/c)2. The sharp forward peak observed previously at lower energies is also present at momenta up to 65 GeV/c; however the s dependence of the cross section is slowing down.
