Abstract

We present a new determination of the ratio of cross-sections as expected for nucleus-nucleus reactions if 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 recent Pb-Pb results from experiment NA50.
