Recent results of E866 on hadron production in Au+Au reaction at AGS energies

Data of hadronic particle production in Au+Au reactions at E/A=11.6 GeV has been measured. A systematic presentation for proton spectra in central reactions is made, as well as the rapidity distributions of particle yields for pions and protons Centrality dependence of spectra for pions, protons, and deuterons is discussed. These results imply there is a large degree of stopping and a subsequent radial expansion in central Au+Au reactions. 9 refs., 4 figs
