Abstract

The multiplicity and pseudo-rapidity distributions of hadrons produced in central collisions of 4.1 A GeV c-1 22Ne nuclei in nuclear emulsion are studied. The KNO scaled multiplicity distribution of the produced hadrons is compared with the predicted distributions according to the Lund model, dual parton model (DPM) and the negative binomial law. The negative binomial method seems to offer a better representation of the experimental data at 4.1 A GeV c-1. The energy density is calculated according to the Bjorken model and found to be less than the estimated energy density required for the transformation into the quark-gluon plasma phase.
