Abstract

We have measured deconfined hadronic volumes, 4.4 < V < 13.0 fm³, produced by one-dimensional(1D) expansion. The volumes are directly proportional to the charged particle pseudorapidity densities 6.75 < dN_C/dn < 20.2. The hadronization temperature is T = 179.5 +/- 5.0 (syst) MeV. The hadronization energy density is epsilon = 1.10 +/- 0.26 GeV/fm³, corresponding to an excitation of 24.8 +/- 6.2 quark-gluon degrees of freedom.
