Abstract

An analytically calculable model [1] has been proposed recently for the simultaneous description of particle spectra and correlations, which is able to explain in a natural manner them t scaling of the radius parameters of the Bose-Einstein correlation functions. We present herepreliminary results on fitting this model to data sampled by NA44 collaboration in central S+Pb reactions at CERN SPS, which indicate that both pions and kaons freeze-out at a surprisingly low temperature ofT≅108 MeV.
