摘要：

Antiproton production cross sections have been measured in minimum bias p + Be, p + Al, p + Cu, and p + Au collisions at 14.6 GeV/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 pBAR production for p + Be is somewhat lower than an estimation based upon 19-24 GeV/c p + p data. In this rapidity interval the antiproton yield scales by a factor of 28+/-6 from p + Au to central Si + Au collisions.
