摘要：

The production of low mass dimuons has been measured in Pb-Pb collisions at the SPS (CERN). (phi/(rho+omega)) ratios have been studied with respect to the centrality of the collision. Preliminary results on phi and (rho+omega) multiplicities as a function of the number of participants are presented. Values for the temperature T are deduced from the cross sections studies in the limited transverse mass M-t domain covered by the experimental apparatus.
