The average multiplicity of light nuclei and pi-mesons, emitted in HeC and CC interactions at 4.2 A GeV/c were studied as a function of number of identified protons. In both interactions, the behavior of average multiplicity of pi- mesons are in agreement with results coming from the Cascade model. The model could not describe the behavior of average multiplicity of light nuclei produced in HeC interactions. In case of CC interactions the model could describe qualitatively the behavior of the average multiplicity of light nuclei. An essential deviation was observed in some of the most central events. We believe that nuclear coalescence effect may be a reason of this deviation.
