    "abstract": "We present numerical results for the dissociation cross sections of\nground-state, orbitally- and radially-excited charmonia in collisions with\nlight mesons. Our results are derived using the nonrelativistic quark model, so\nall parameters are determined by fits to the experimental meson spectrum.\nExamples of dissociation into both exclusive and inclusive final states are\nconsidered. The dissociation cross sections of several C=(+) charmonia may be\nof considerable importance for the study of heavy ion collisions, since these\nstates are expected to be produced more copiously than the J/psi. The relative\nimportance of the productions of ground-state and orbitally-excited charmed\nmesons in a pion-charmonium collision is demonstrated through the $\\sqrt\n{s}$-dependent charmonium dissociation cross sections.",
