    "abstract": "We report on global fits of optical-model parameters to 90 data points for\n$\\bar p$ X-rays and 17 data points of radiochemical data put together. With the\nhelp of separate fits to the two kinds of data it is possible to determine\nphenomenologically the radial region where the absorption of antiprotons takes\nplace and to obtain neutron densities which represent the average behaviour\nover the periodic table. A finite-range attractive and absorptive $\\bar\np$-nuclear isoscalar potential fits the data well. Self-consistent dynamical\ncalculations within the RMF model demonstrate that the polarization of the\nnucleus by the {\\it atomic} antiproton is negligible.",
