    "abstract": "Last year the E866-group of the Fermilab measured the $x_F$ dependence of\n$J/\\Psi$ and $\\Psi\u0027$ suppression in $pA$ collisions. We discuss two of the\neffects found in that experiment with regard to color coherence effects: the\ndifferent suppression of the $J/\\Psi$ and the $\\Psi\u0027$ at $x_F\u003c0$ and the\nsignificant suppression of both at large $x_F$. The small $x_F$ regions is\ndominated by fully formed charmonium states and thus enables us to discuss the\nformation time and the cross section of the different charmonium states. In the\nlarge $x_F$ region the interaction of the charmonium states with nuclear matter\nhas to be described by partonic degrees of freedom, because in that kinematic\ndomain the formation time is much larger than the nuclear radii. The\nunderstanding of this region will be crucial for the interpretation of the data\nof the future heavy ion colliders RHIC and LHC.",
