    NA50 EIWe present a new determination of the ratio of cross-sections (J/ψ\psi)/DY as expected for nucleus-nucleus reactions if J/ψ\psi would only be normally absorbed by nuclear matter. This anticipated behaviour is based on proton-nucleus data exclusively, and compared, as a function of centrality, with updated S-U results from experiment NA38 and with the most Pb-Pb results from experiment NA50
