Multifragmentation of target in Si-28-AgBr interactions at 14.5 A GeV - self affine or self similar

摘要

Nature of dynamical fluctuations of target evaporated slow particles is investigated in both forward and backward emission angular zones in the framework of multi-dimensional factorial moment methodology using the concept of Hurst exponent. Our analysis on target fragments emitted in Si-28-AgBr interactions at 14.5 A GeV reveals the hint of self-affine dynamical fluctuations in the forward emission angular zone. However in the backward emission angular zone it cannot be unambiguously stated whether the nature of dynamical fluctuations is self affine in nature or self similar. This work further shows the presence of stronger intermittent type of fluctuations in the forward hemisphere. (C) 2003 Elsevier Science B.V. All rights reserved. [References: 26]
