AbstractAbstract
[en] The π-+A→Λ+kp+X(k=0,1,2,...) and πsup(-)+A→ kpsub(back)+X(k=1,2...) reactions are investigated at 3.9 GeV/c π--meson. The data are obtained on 105 cm freon bubble chamber. In the πsup(-)+A→ kpsub(back)+X reaction pair correlations af fast protons with similar momenta are observed. The comparison of differential invariant cross sections with the predictions by the nuclear fireball model is made. The secondary Λ-hyperon polarization has been measured. The dependence on kinematic variables of polarization of Λ-hyperons, which are not accompanied by proton emission, coincides with the function obtained at the production of hyperons on free nucleons
