We present the results of a study of hadronic jets produced in association with direct photons and π0's at large transverse momenta in π-Be and pBe collisions at 500 GeV/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 γ and π0 event samples. We also compare the data with QCD calculations that incorporate current parton distribution functions.
