The interaction of antiprotons with nuclei is investigated in a model using the free space T-matrix and nuclear densities from HFB calculations. Elastic scattering and annihilation reactions are used as probes for nuclear sizes of exotic nuclei. The annihilation cross sections are related to the nuclear root-mean-square radii by a scaling law. A more detailed picture is obtained by detecting in coincidence a pion ejected from the annihilation zone.
