    "abstract": "We discuss the production of charmonium states in antiproton-nucleus\ncollisions at the $\\psi\u0027$ threshold. It is explained that measurements in $\\bar\np A$ collisions will allow to get new information about the strengths of the\ninelastic $J/\\psi N$ and $\\psi\u0027N$ interaction, on the production of $\\Lambda_c$\nand $\\bar{D}$ in charmonium-nucleon interactions and for the first time about\nthe nondiagonal transitions $\\psi\u0027 N\\to J/\\psi N$. The inelastic\n$J/\\psi$-nucleon cross section is extracted from the comparison of\nhadron-nucleus collisions with hadron-nucleon collisions. Predictions for the\nratio of $J/\\psi$ to $\\psi\u0027$ yields in antiproton-nucleus scatterings close to\nthe threshold of $\\psi\u0027$ production for different nuclear targets are\npresented.",
