The main experimental characteristics multiplicity have been investigated from 28Si with emulsion at 4.5 GeV/c. The nucleus-nucleus collisions are given in the energy interactions of 4He, 24Mg and 28Si with emulsion nuclei at nearly the same. On the other hand the relativistic energy (a few GeV/nucleon) is a special energy, at which the nuclear limiting fragmentation applies initially. Therefore, the target fragmentation is studied by selecting samples of inelastic interactions events having no emission of relativistic hadrons'. The multiplicity distribution of the produced target fragments are studied. The angular distribution of target fragmentations particles, grey and black of the interaction of 28Si emulsions, shows statically significant peak which have been attributed to a collective phenomenon.
Keywords: Multiplicity secondary particles, Multiplicity correlation and angular distribution
