OSTI ID:10161200
We present results on antiproton production obtained in the AGS experiments E858 and preliminary results of E878. The yields of antiprotons in Si + A collisions are shown to sale with number of first collisions. The rapidity distributions for all targets (Au, Cu and Al) and both beams (si at 14.6 GeV/c and A at 11. GeV/c) have gaussian shapes peaking at y{sub NN} and with similar standard deviations. From E878 we report a difference in the shape of the antiproton rapidity distributions obtained from two samples of the data populated with central and peripheral events respectively. In A induced reactions the A dependence of the antiproton yields is small.
