Inclusive production cross sections have been measured for the processes p-italic+A-italic..--> gamma../sup 0/+X (A-italic = Be, Cu, Pb) and for p-italic+Be..-->..Xi-bar/sup 0/+X. Data were taken at angles of 0, 2, 3.5, 7.3, and 9.8 mrad between the incident 400-GeV proton beam and the outgoing hyperon beam. Production cross sections for ..lambda.. and Lambda-bar production were measured at the same time. The A-italic dependence of the ..gamma../sup 0/ cross sections is discussed, along with interpretations in terms of various models.
