Abstrakt: Data on Λ's and K'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 $$\bar \Lambda /\Lambda $$ production ratio was estimated to be ≤10 with a 90% confidence level. The results are compared with data of other experiments and some model calculations. [ABSTRACT FROM AUTHOR]
