Description

Data on Λ's and K0's, produced in central nucleus - nucleus collisions (C-C, C-Ne, O-Ne, C-Cu, C-Zr, C-Pb, O-Pb) at a 4.5 GeV/c momentum per incident nucleon obtained in the streamer chamber spectrometer SKM-200, are presented. Multiplicities, transverse momenta, rapidities and other characteristics are considered and compared with those for inelastic He-Li interactions. The polarization of Λ's was found to be consistent with zero. The upper limit of Λ/Λ production ratio was estimated to be proportional10-2 with a 90% confidence level. The results are compared with data of other experiments and some model calculations. (orig.)
