摘要：

First results are reported on J/psi and Drell-Yan cross-sections in Pb-Pb reactions at 158 GeV/c per nucleon. The ratio of cross-sections sigma(J/psi)/sigma(DY) is studied as a function of the impact parameter of the collision estimated from the measured transverse energy. (C) 1997 Elsevier Science B.V.
