With the PANDA detector at the HESR at FAIR it will be possible to study the production of charmed hadrons on nuclear targets. One reactions of particular interest is the formation of J/Psi mesons when a nuclear target is bombarded with antiprotons. If the momentum of the incident antiprotons is properly selected, then they can annihilate with protons in the nucleus of a target atom and form a J/Psi meson. The formed J/Psis have relatively small momenta with respect to the nucleus and therefore act as a probe of the nuclear medium. In this talk I will report on a study of the possibility to measure with PANDA the probability for the J/Psi mesons to be dissociated before they escape from the nucleus. This nuclear dissociation cross-section is relevant for the interpretation of the J/Psi suppression observed in high energy heavy ion reactions, a possible signature of the existence of a quark-gluon plasma.
