| Abstract: | Based on the theory of independent source model, the charged-multiplicity distributions in heavy ion collisions are derived which are then used to analyze the centrality dependence of the charged-multiplicity pseudo-rapidity densities, dnch/dη, in Au+Au collisions at (SNN)1/2=130 GeV in midrapidity region. The theoretical results agree well with experimental facts. |
