heal.abstract	The associated charged particle multiplicities of high-pT π0 and single-photon events were measured at the CERN intersecting storage rings using lead/liquid-argon calorimeters and a scintillation counter array placed around the intersection region. The average multiplicity on the trigger side for the single-photon events was found to be significantly lower than that for the π0 events. The away-side multiplicity for both π0 and single-photon events increases with the trigger particle pT, but, at a fixed pT, the direct photon sample was found to have a slightly lower average multiplicity. The differences in the event structure can be explained if a large fraction of the single photons are produced via qg → γq constituent scattering. © 1980.	en
