This thesis describes a study of the production of high transverse momentum direct photons and [pi]0 mesons by proton beams at 530 and 800 GeV/c and [pi]- beams at 515 GeV/c incident on beryllium, copper, and liquid hydrogen targets. The data were collected by Fermilab experiment E706 during the 1990 and 1991-92 fixed target runs. The apparatus included a large, finely segmented lead and liquid argon electromagnetic calorimeter and a charged particle spectrometer featuring silicon strip detectors in the target region and proportional wire chambers and drift tubes downstream of a large aperture analysis magnet. The inclusive cross sections are presented as functions of transverse momentum and rapidity. The measurements are compared with next-to-leading order perturbative QCD calculations and to results from previous experiments.

Results are presented on the production of high transverse momentum $\pi \sp0$ mesons from hard scattering collisions of hadrons incident on a nuclear target. The inclusive $\pi \sp0$ production cross-sections were measured as a function of $p\sb{T}$ for $p, \pi \sp+$ and $K\sp+$ incident on beryllium targets. These data were recorded by Fermilab experiment E706 during the 1991 data acquisition period. The $\pi \sp0$ mesons were detected as pairs of high $p\sb{T}$ photons which produced electromagnetic showers in a finely segmented lead-liquid argon calorimeter. The unseparated incident beam particles were identified using the Meson West beamline Cerenkov detector. The measured cross-sections are presented for $\pi \sp0$ mesons in the rapidity range ${-}0.75 y
