In $\\bar p + \\text{Au}$ collisions at $6-10$ GeV we study their in\\,-\\,medium propagation. The time evolution of the spectral functions of these charmonium states is studied with a Boltzmann\\,-\\,Uehling\\,-\\,Uhlenbeck (BUU) type transport model. We show that their in\\,-\\,medium mass shift can be observed in the dilepton spectrum.
