The nuclear dependence of inclusive direct photon production and inclusive neutral meson production by a 515 GeV /c 71"-beam has been measured using data collected by the E706 experiment during the 19.90 fixed, target run at the Fermi National Accelerator Laboratory. The experiment utilized a finely segmented liquid argon calorimeter and a high precision charged particle spectrometer to make precision measurements of inclusive direct photon, neutral pion, and T/ production in the rapidity interval from -0. 75 < y < 0. 75. The 71" 0 data is reported for the PT range from 0.
