Popis: Using the simulation data coming from the cascade model, we have studied the behavior of event number as a function of impact parameter-b and a number of all charged particles- Nch for light and heavy nuclei at different energies. We have seen that for light nuclei, a number of all charged particles-Nch could be used to fix the centrality. But for heavy nuclei we have got strong initial energy and mass dependences and the results for impact parameter factor dependences and ones for a number of all charged particles differ. So for heavy nuclei, a number of charged particles-Nch could not be use to fix the centrality. Key words: cascade model; centrality, light nuclei, heavy nuclei
