Resumen

Antiproton production near midrapidity has been studied in central collisions of 32S with sulphur, silver and gold nuclei at 200 GeV per nucleon. The measured transverse mass distributions can be described by an exponential with inverse slope parameters of about 200 MeV, similar to those obtained from Λ̄ spectra. The rapidity density increases weakly with the target mass, ranging from 0.4 to 0.7. The ratio Λ̄/p̄ near midrapidity is approximately 1.4 on average, significantly larger than the corresponding ratio observed in proton-proton and proton-nucleus collisions.
