The behavior of the relativistic hadron (shower particle) multiplicity for [sup 32]S-nucleus interactions is investigated. The experiment is carried out at 3.7A GeV (Dubna energy) and 200A GeV (SPS energy) to search for the incident energy effect on the interactions inside the different emulsion target nuclei. Data are presented in terms of the number of emitted relativistic hadrons in both forward and backward angular zones. The dependence on the target size is presented. For this purpose the statistical events are separated into groups according to the interactions with H, CNO, Em, and AgBr target nuclei. The forward shower particle multiplicity distributions may behave in a similar trend at Dubna energy and SPS for low target sizes. For heavy target sizes, the SPS energy reveals the creation of hadrons with nearly equal probabilities over a wide range of multiplicity, extending to more than 300 hadrons per event. The data are analyzed in the framework of the FRITIOF model.
