Abstract: (Elsevier)

The production of long-lived negative secondaries, including π − , K − , antiprotons ( p ) and antideuterons ( d ) at 0° in Si+Au, Si+Cu, and Si+Al collisions at the BNL-AGS has been measured using a double-bend, double-focussing spectrometer. The p rapidity spectra from all three targets are well fit by Gaussians centered ( y = 1.7 − 1.8 ) at mid-rapidity, and are consistent with production in nucleon-nucleon first collisions. The d p 2 ratio in Si+Au collisions is lower by a factor of 10 than that seen in p+p and p+A collisions.
