Structure of the recoiling system in direct-photon and pi 0 production by pi - and p beams at 500 GeV/c.

We present the results of a study of hadronic jets produced in association with direct photons and [pi][sup 0]'s at large transverse momenta in [pi][sup [minus]]Be and [ital p]Be collisions at 500 GeV/[ital c]. Using primarily charged particles to characterize the properties of the recoiling jets, we compare their fragmentation and angular distributions, and their correlation with the trigger particle, for both the [gamma] and [pi][sup 0] event samples. We also compare the data with QCD calculations that incorporate current parton distribution fuctions.
