摘要：
The rapidity distributions of particles produced in nucleus-nucleus (Au-Au) collisions at the Alternating Gradient Synchrotron (AGS) energy (11-15A GeV) have been analyzed by the thermalized cylinder model and the three-fireball model. It is shown that the two models are successful at the AGS energy. The normalized rapidity distributions of produced particles (exclusion of protons) described by the two models do not depend on the forward energy and multiplicity. The rapidity shifts in the two models do not depend on the impact parameter. The proton and deuteron normalized rapidity distributions contributed by the participants in Au-Au collisions do not depend on the forward energy and multiplicity, but the final state proton and deuteron rapidity distributions depend on the forward energy and multiplicity due to the contributions of spectators.
