Abstract: 
The charmonium dissociation by mesons, in relativistic heavy-ion reactions, is analyzed within the Regge approach. It is shown that, the inclusion of the initial and final state interactions in the dissociation of J/Psi to (D) over bar *D* close to threshold increases the cross section significantly and can not be neglected in comparison to the total dissociation rate. This is due to resonant (D) over bar*-D* interactions in root s close to the masses of the Psi(4.04) and Psi(4.16) mesons. We also investigate thermal effects of the (c (c) over bar) width for such processes in the medium. All these effects change both the magnitude and the shape of the cross section as a function of root s. The results obtained should be applied in the analysis of open and hidden charm production in heavy-ion collisions.
