Abstract
A Fermi statistical model analysis of hadron abundances and spectra obtained in several relativistic heavy ion collision experiments is utilized to characterize a particle source. Properties consistent with a disintegrating, hadron evaporating, deconfined quark-gluon plasma phase fireball are obtained, with a baryochemical potential \mu_B=200-210MeV, and a temperature T_f\simeq 140-150MeV, significantly below previous expectations.
