Abstract Interactions of 40 GeV/c πp-,K − and $$\bar p$$ on Li, C, S, Cu, CsI and Pb were studied with the RISK-streamer chamber spectrometer. We present multiplicities of negatively charged particles, as well as of protons, and the correlations between them. The normalized mean multiplicity of negative particles,R −, depends on $$\bar v$$ , the average number of inelastic collisions as $$R^ - = (0.73 \pm 0.04) + (0.34 \pm 0.02)\bar v$$ . The dependence of the normalized dispersion of negative particles,D −/〈N −〉, on the number of protons favours independent collision models and contradicts the coherent tube picture. The excess of fast positive particles behaves asA 0.4 and shows, for the heavier nuclei, a clear correlation with identified protons.
