Abstract
Semi-inclusive proton and pion distributions from central Au+Au reacti ons at 11.6A GeV/c have been measured. The proton rapidity distributio n shows significantly increased stopping compared to lighter systems, providing strong evidence for the formation of a state of matter with baryon density substantially greater than normal nuclear matter. Unlik e reactions at this energy induced by lighter heavy ions, at low m(1)- m(0) the proton invariant spect a deviate from a single exponential sh ape and become flatter, while pi(-) spectra are found to rise faster t han the pi(+) spectra.
