Interactions induced by 200 GeV per nucleon 32 S ions on heavy targets were selected by the HELIOS calorimeters and studied in nuclear emulsions. Global observables, such a s c harged particle multiplicity and transverse energy, w ere determined event-by-event. Multiplicity and transverse energy were measured as a function of the pseudorapidity o v er the large acceptance of the present experiment (0.6 5:5). A comparison of the experimental data with those provided by the event generators

An attempt is made to interpret these discrepancies in terms of plausible mechanisms, like baryon-pair production or rescattering. PACS 25.75 -Relativistic heavy-ion nuclear reactions.
