Query: Charmonium absorption by nucleons   $J/\Psi$ dissociation in collisions with nucleons is studied within a boson
exchange model and the energy dependence of the dissociation cross section is
calculated from the threshold for $\Lambda_c{\bar D}$ production to high
energies. We illustrate the agreement of our results with calculations based on
short distance QCD and Regge theory. The compatibility between our calculations
and the data on $J/\Psi$ photoproduction on a nucleon is discussed. We evaluate
the elastic $J/\Psi{+}N$ cross section using a forward dispersion relation and
demonstrate the overall agreement with the predictions from QCD sum rules. Our
results are compatible with the phenomenological dissociation cross section
evaluated from the experimental data on $J/\Psi$ production from $\gamma{+}A$,
$p{+}A$ and $A{+}A$ collisions.
