Abstract

We present a Monte-Carlo simulation of energy deposition process in relativistic heavy-ion collisions based on a new realization of the Interacting-Gluon-Model (IGM) for high energy N-N collisions. In particular we show results for proton spectra from collisions of Elab=200 \ GeV/N 32S beam incident on 32S target and analyze the energy and mass dependence of nuclear stopping power predicted by our model. Theoretical predictions for proton rapidity distributions of both 208Pb + 208Pb collisions at Elab=160 \ GeV/N CERN SPS and 197Au + 197Au at sNN=200 \ GeV BNL RHIC are given.
