Abstract
An excitation function of proton rapidity distributions for different centr alities is reported from AGS Experiment E917 for Au + Au collisions at 6, 8 , and 10.8 GeV/nucleon. The rapidity distributions from peripheral collisio ns have a valley at midrapidity which smoothly change tr, distributions tha t display a broad peak at midrapidity for central collisions. The mean rapi dity loss increases with increasing beam energy, whereas the fraction of pr otons consistent with isotropic emission from a stationary source at midrap idity decreases with increasing beam energy. The data suggest that the stop ping is substantially less than complete at these energies.
