Ferenc, D. Universal pion freeze-out phase-space density / D. Ferenc ... [et al.]. -- Results on the pion phase-space density at freeze-out in sulphur-nucleus, Pb-Pb and pi-p collisions at the CERN SPS are presented. All heavy-ion reactions are consistent with the thermal Bose-Einstein distribution f = [exp( E/T) 1](-1) at T similar to 120 MeV, modified for radial expansion. pi-p data are also consistent with f, but at T similar to 180 MeV and without radial flow.
