Abstract

The multiplicity distribution of the target-evaporated black particles emitted in the interactions of 16O beams with emulsion nuclei at 60A and 200A GeV in both the forward and backward hemispheres are examined. The asymmetry parameters, the forward–backward ratios as well as multiplicity distribution moments are evaluated. The investigated scaled variances and the second Mueller moments are observed to indicate the strongly correlated emission of target-evaporated black particles in the forward direction. The ratio of entropy to average multiplicity of target fragments is evaluated, and is found to be energy-independent in both the forward and backward hemispheres.
