Abstract : The production of dimuon in Pb-Pb collisions at 158 GeV/c per nucleon has been measured at the CERN SPS in experiment NA50. An anomalous suppression of J/¢ production cross section has been observed in comparison with the value expected from the results obtained in proton and light ion induced reactions. An analysis of the transverse momentum distribution of J/¢ is presented. For J/¢ production, < p~ > values have been calculated as a function of centrality.
