In 1988 experiment E706 at Fermilab wrote approximately 6 million triggered events to tape. The purpose of this was to measure the cross sections for high p [perpendicular] [pi][sup 0] and single photon production. In addition, the cross sections were to be measured for proton and [pi][sup [minus]] beams on a variety of nuclear targets. To achieve these goals the experiment had been furnished with a large liquid argon calorimeter. A magnetic spectrometer for studying the associated product of charge particles had been built as well. The purpose of this analysis is to compare the associated charged particle structure of high p [perpendicular] [pi][sup 0] and direct photon events to see if they are indeed different. The current theory of hadron-hadron interactions, quantum chromodynamics, makes a number of predictions indicating that they are. The charged particles recoiling from a high p [perpendicular] [gamma] or [pi][sup 0] trigger will be used to reconstruct the [pi][sup 0] + jet and [gamma] + jet angular and invariant mass distributions for this study. Finally, the invariant mass distributions will be employed to study the gluon structure functions of hadrons.
