Abstract

The ratio dE_T \over dη / dN_ch \over dη is analyzed in the framework of a single-freeze-out thermal hadron gas model. Decays of hadron resonances are taken into account in evaluations of this ratio. The predictions of the model at the freeze-out parameters, established previously from observed particle yields, agree very well with the ratio measured at RHIC, SPS and AGS.
