摘要：
An attempt is made to study the existence of non-statistical fluctuations of relativistic particles using the method of scaled factorial moments (SFMs) in the interactions of Si-28 and C-12 nuclei at 4.5 A GeV/c with nuclear emulsion. The experimental result has also been compared with FRITIOF generated data. The analysis of SFMs gives an evidence for an intermittency pattern of fluctuations. The increasing trend of anomalous fractal dimensions, d(q), of the pseudo-rapidity distribution with the order of the moment, q observed in the present study supports a self-similar cascade mechanism. The results for experimental data are quite consistent with those obtained for FRITIOF data. Finally, it can be concluded that no universality in the values of the multifractal specific, c, is found for our data.
