Multiparticles; proton emission; rapidity; attenuation of the leading pion; parton-model; rescattering effect

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 〈N_s⁺−N_s⁻〉 produced in the final state of the reaction rises rapidly from a negative to a positive value atN_h⩽1 and attains a constant value⋍0.60±0.08 at allN_h⩾7.
