Abstract

In the presented paper curves of constant ε_T / n_charged are calculated in T-μ_B plane, in the framework of a single-freeze-out thermal hadron gas model. The ratio is a theoretical equivalent of dE_T \over dη_{| η=0} / dN_ch \over dη_{| η=0} measured at RHIC and SPS. In both ε_T and n_charged decays of hadron resonances are taken into account. The freeze-out temperature T_f.o.=156_-11⁺¹⁴ MeV is obtained for RHIC, whereas T_f.o.=134-140 MeV is evaluated for SPS.
