Preliminary data are presented for the production of antiprotons and other charged particles produced in minimum bias and central Si + Al and Si + Au collisions measured using the E802 spectrometer at the Brookhaven Alternating Gradient Synchrotron. The antiproton data presented cover the range of transverse momentum from 0.3 to 1.2 GeV/c and lab rapidities from 0.9 to 1.7. The extracted rapidity densities, transverse mass slopes, and particle ratios from minimum bias and central Si + A collisions are compared to those measured in p + p and p + A collisions.
