Abstract
The multiplicity distributions of a particles emitted in nucleus-nucle us collisions occurring in photoemulsion are analyzed for C-12, N-14, Ne-22, Mg-24, Si-28, and F-56, projectiles with momenta between 2.5 an d 4.5 GeV/c per nucleon. For all projectiles considered in this study, the shape of the multiplicity distributions is found to obey neither a universal law similar to that prescribed by the Koba-Nielsen-Olesen scaling nor the Poisson law. Qualitatively, the results agree with the percolation model and may suggest that the fragmentation of nuclei in volves a phase transition.
