Abstract We report on a systematic study of midrapidity transverse energy production and forward energy flow in interactions of16O and32S projectiles with S, Cu, Ag and Au targets at 60 and 200 GeV/nucleon. The variation of the shape of theE T distributions with target and projectile mass can be understood from collision geometry. AverageE T values determined for central collisions show an increasing stopping power for heavier target nuclei. A higher relative stopping is observed at 60 GeV/nucleon than at 200 GeV/nucleon. Bjorken estimates of the energy density reach approximately 3 GeV/fm3 in highE T events at 200 GeV/nucleon with16O and32S projectiles. The systematics of the data and the shapes ofE T and pseudorapidity distributions are well described by the Lund model Fritiof.
