Annotation

Suppression of birth of $J/\Psi$ charmonium in collisions of heavy ions was observed in several experiments. This phenomenon can be a consequence of formation of quark-gluon plasma, charmonium-hadron collisions, and nuclear absorption effects. Therefore, of interest is the dissociation of quarkonium in quark-gluon plasma. In this communication, calculations are carried out for the processes $J/\Psi+g \to c+\bar{c}$ and $\Upsilon + g \to b+\bar{b}$ at various temperatures.
