The momenta and rapidity characteristics of the particles produced in 50 GeV/cπ−-collision with emulsion nuclei have been studied with an emulsion stack exposed under a pulsed magnetic field. The longitudinal rapidity plots suggest that leading pion is attenuated strongly when passing through a heavy nucleus. The average net charge 〈Ns+−Ns−〉 produced in the final state of the reaction rises rapidly from a negative to a positive value atNh⩽1 and attains a constant value⋍0.60±0.08 at allNh⩾7.
