Transverse momenta and rapidities of ..lambda..'s produced in central nucleus-nucleus collisions at 4.5 GeV/cxu (C--C,..., O--Pb) were studied and compared with those from inelastic He-Li interactions at the same incident momentum. Polarization of the ..lambda.. hyperons was found to be consistent with zero (..cap alpha..P = -0.06 +- 0.11 for ..lambda..'s from central collisions). An upper limit of the Lambda-bar/..lambda.. production ratio was estimated to be less than 4.5 x 10/sup -3/. The experiment was performed in a triggered streamer chamber.
