Abstract
Transverse mass spectra of pions, kaons, and protons from the symmetri c heavy-ion collisions 200A GeV S + S and 158A GeV Pb + Pb, measured i n the NA44 focusing spectrometer at CERN, are presented. The mass depe ndence of the slope parameters provides evidence of collective transve rse flow from expansion of the system in heavy-ion induced central col lisions.
