    "abstract": "A mechanism for the effective dissociation of a $c\\bar{c}$ pair in the colour\nelectric field of strings is introduced into a hadron and string cascade model,\ni.e. JPCIAE, which is based on the LUND model, simulating ultra-relativistic\nnucleus - nucleus collisions. This new mechanism together with the known\nmechanism of nuclear absorption (both baryons and mesons) could reproduce\nfairly the data of the normal and anomalous $J/\\psi$ suppressions in minimum\nbias pA, AB (with light projectile), and Pb + Pb collisions at 200 A GeV/c.\nHowever the impact parameter (E_T) dependence of the $J/\\psi$ suppression\nfactor, both, in S + U and Pb + Pb reactions at 200 A GeV/c and 158 A GeV/c,\nrespectively, is not well reproduced. We also tested the additional mechanism\nof the energy degradation of leading particles, with which both, the normal and\nanomalous $J/\\psi$ suppressions in minimum bias pA, AB, and Pb + Pb collisions\nand the E_T dependence of the $J/\\psi$ suppression factor are better\nreproduced.",
