摘要：

Results from the WA85 Experiment at the CERN Ω Spectrometer are presented. A 200 A GeV/c beam of 32S ions was used with a tungsten target. The apparatus is used to detect V0,s and charged tracks in the range pT > 0.9 GeV/c and 2.3 < Ylab < 3.0. Production of Λ, Λ and negative hadrons all show a linear increase with rapidity density in the range 70-140 as expected from models based on a superposition of independent NN collisions. © 1990.
