The differential cross sections for γp→γp and γp→π0p have been measured for incident photon energies in the range of 2 to 6 GeV and for |t| ranging from 0.7 to 4.3 GeV2. This corresponds to a center-of-mass angle range of 45° to 128°. The energy dependence of the data is compared to that predicted by several parton models.

We report a high-statistics measurement of the neutron-proton charge-exchange differential cross section for incident momenta 3 to 12 GeVc, and four-momentum transfers 0.003 to 0.85 (GeVc)2. The data are normalized absolutely to ±20%. The differential cross section is characterized by a sharp peak at small momentum transfers, with a gentler exponential behavior at large momentum transfers. This shape is remarkably independent of the incident momentum.
