Away and Trigger Hemisphere charge asymmetry and Away and Trigger Regions track multiplicity in direct ..gamma.. and ..pi../sup 0/ events produced in pBe collisions have been studied. No significant difference in charge asymmetry was found between direct ..gamma.. and ..pi../sup 0/ events. In both direct ..gamma.. and ..pi../sup 0/, the charge asymmetries showed a trend towards higher values with increasing trigger particle P/sub t/ for the Away Hemisphere, and towards lower values for the Trigger Hemisphere. No significant difference was observed in the direct ..gamma.. and ..pi../sup 0/ events particle multiplicity, except for the Away Region tracks with P/sub t/ above 0.5 GeV/c. In the latter case, ..pi../sup 0/ events showed higher track multiplicity for trigger P/sub t/ above 4.5 GeV/c. In general, the Away Region had higher track multiplicity than the Trigger Region.
