Abstract

We have measured the neutron-proton charge-exchange differential cross section in the momentum interval 60 to 300 GeV/c, with squared four-momentum transfers 0.002 to 0.8 ${(G e V / c)}^{2}$ . Independent of incident momentum, the data are characterized by a sharp forward peak of width 0.02 ${(G e V / c)}^{2}$ , followed by a shoulder and gentler falloff at higher momentum transfers.
