In this work the fast target fragments from high multiplicity interactions of 16O (at 60A GeV and 200A GeV) and 32S (at 3.7A and 200A GeV) ions with Ag (Br) targets have been measured. The characteristics of these interactions have been compared to those from simulations using the Modified FRITIOF Code. The comparison indicates that there is a need to modify the code and incorporate a greater amount of rescattering for a better fit to the experimental data. The multiplicity distributions for all interactions have been fitted well with the Gaussian distribution function. The measurements of the scaled variance (ω >1) show that the production of target fragments at high energies cannot be considered as a statistically independent process. The energy dependence of entropy is examined. The entropy values normalized to average multiplicity (S /< Ng >) are found to be energy independent. The possibility of scaling, i.e., similarity in the multiplicity distributions of grey tracks produced in nucleus-nucleus interactions has been examined. A simplified universal function has been used to display the experimental data. The relationship between the entropy, the average multiplicity and the KNO function is examined as well.
