摘要：
An attempt is made to investigate occurrence of nonstatistical fluctuations in terms of intermittency in O-16-AgBr interactions at 4.5, 14.5, 60 and 200A GeV/c. Additionally, mixed and AMPT generated events are also analyzed. Normalized factorial moments, F-q, are calculated and their variations with pseudorapidity resolution, delta eta, are investigated. Various important parameters like intermittency indices, anomalous dimensions, Renyi dimensions and Levy indices are calculated and interpreted. Comparison of the experimental results with the results obtained for the mixed and AMPT events suggests that the intermittency pattern observed in the experimental data is a manifestation of some dynamical phenomena and not due to statistical fluctuations.
