Abstract
The multiplicity and pseudo-rapidity distributions of hadrons produced in central collisions of 4.1 A GeV c-1 Ne-22 nuclei in nuclear emulsi on are studied. The KNO scaled multiplicity distribution of the produc ed hadrons is compared with the predicted distributions according to t he 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 calcula ted according to the Bjorken model and found to be less than the estim ated energy density required for the transformation into the quark-glu on plasma phase.
