We evaluate the nonperturbative part of these cross sections which dominates at $\\sqrt{s_{NN}}\\approx 20$ GeV at the Cern Super Proton Synchrotron (SPS) and becomes a correction at $\\sqrt{s_{NN}}\\approx 6$ TeV at the CERN Large Hadron Collider (LHC). $\\J$ production at the CERN SPS is well described by hard QCD, when the larger absorption cross sections of the $\\chi$ states predicted by QCD are taken into account.
