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.

The total and elastic cross sections for antineutrons on protons have been measured for antineutron momenta from 0.5 to 2.5 GeV/c. The results are in agreement with previous p¯p data at these momenta.
