Abstract
The NA50 Collaboration has performed a new measurement of the J/ψ yield in Pb-Pb collisions at 158 GeV/nucleon in improved experimental conditions. Our preliminary analysis of the year 2000 data sample, while confirming the onset of anomalous suppression and the non saturation of the J/ψ/Drell-Yan cross-section ratio, shows that peripheral Pb-Pb interactions follow the normal nuclear absorption pattern, which has in turn been established more precisely thanks to high statistics p-A data.
