    "abstract": "We propose a method to estimate the entropy of thermal pions in A+A\ncollisions irrespective of unknown form of freeze-out (isothermal) hypersurface\nand transverse flows developed. We analyse the average phase-space densities\nand entropies of the thermal pions vs their multiplicities and collision\nenergies. The behaviour of these values apparently indicates the deconfinement\nand chiral phase transitions in relativistic nuclear-nucleus collisions",
