Abstract
We study suppression in Pb+Pb collisions at CERN-SPS energies in hadronic matter with energy- and temperature-dependent charmonium dissociation cross sections calculated in the quark-interchange model of Barnes and Swanson. We find that the variation of J/ survival probability from peripheral to central collisions can be explained as induced by hadronic matter absorption in central collisions.
