HADRON DISTRIBUTIONS - RECENT RESULTS FROM THE CERN EXPERIMENT NA44

Proton distributions at midrapidity have been measured for 158A . GeV Pb+Pb collisions in the focusing spectrometer experiment NA44 at CERN. A high degree of nuclear stopping is found in the truly heavy ion col lisions. Systematic results of single particle transverse momentum dis tributions of pions, kaons, and protons, of 200A . GeV S+S and 158A . GeV Pb+Pb central collisions will be addressed within the context of t hermalization. By comparing these data with thermal and transport mode ls, freeze-out parameters such as the temperature parameter T-fo and m ean collective flow velocity (beta) are extracted. Preliminary results of the particle ratios of K-/K+ and (p) over bar/p are discussed in t he context of cascade models of R&MD and VENUS.
