Antiproton production cross sections have been measured in minimum bias [ital p]+Be, [ital p]+Al, [ital p]+Cu, and [ital p]+Au collisions at 14.6 GeV/[ital c] with the E-802 spectrometer at the Brookhaven Alternating Gradient Synchrotron. The antiproton multiplicity at laboratory rapidities 1.0 to 1.6 shows almost no dependence upon the target mass. The [ital [bar p]] production for [ital p]+Be is somewhat lower than an estimation based upon 19--24 GeV/[ital c] [ital p]+[ital p] data. In this rapidity interval the antiproton yield scales by a factor of 28[plus minus]6 from [ital p]+Au to central Si+Au collisions.
