Measurements ofKs0, Λ and$\bar \Lambda $ production in π− nucleus (C, Cu, Pb) interactions are presented. The experiment was carried out with the streamer chamber spectrometer RISK using a π− beam of ∼40 GeV/c and a trigger requiring a secondary charged particle with transverse momentum above 1.1 GeV/c. Production cross sections, relative production rates and distributions of Feynmanx and transverse momentum squared as well as correlations between theV0 and the trigger particle are presented. The results are compared and found to be in agreement withKs0, Λ and$\bar \Lambda $ data from untriggered π−p and π−C interactions, except for the relative production rate of antilambdas which is about to times larger in high-pt collisions. Our results can be well interpreted within the dual topological unitarization model.

The data on invariant cross sections of deuterons emitted in the interactions of 3He with C, Cu and Pb targets at 4.9 GeV/nucleon are given. Inclusive spectra of deuterons produced in the reactions were measured from 20 deg to 150 deg in the laboratory frame with 10 deg step. Measurements were made on external 3He-beam at Dubna synchrophasotron
