Abstract： A general cascade package is used to handle the J/ψ and ψ production and absorption for different ET bins in S-U and Pb-Pb collisions. We study the combined effect of nuclear absorption and final state interaction with co-movers on the J/ψ and ψ suppression. The experimental data of J/ψ production can be fitted for different ET-bins in S-U collisions and for lower ET-bins in Pb-Pb collisions. However, ψ data for high ET-bins in both S-U and Pb-Pb collisions can not be explained.
