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.
