| Abstract: | The multiplicity distribution of grey particles obtained using the statistical model is compared with the exprimental data from 3.7 AGeV,14.6 AGeV Si induced inter- actions with emulsion nuclei.It is found that the amount of target nuclear matter and the in- tranuclear cascade play the important role for the production of grey particles,the strong correlation between the multiplicity of grey particles n_and the centrality of impact is pre- sented. |
