Abstract

We present a systematic study of transverse energy (ET) production in collisions of 11.4A GeV/c Au and 14.6.A GeV/c Si ions with targets of Al, Au, and Pb. Comparison of data for Au+Au and Si+Al indicates that, for the heavier system, there is an increase in the amount of stopping which is accompanied by a decrease in the width of the dET/dη distribution. The ratio of the maximum ET observed for the two systems is significantly greater than the ratio of the total energy available in the center of mass frame.
