Antiprotons for Nuclear Structure Research

The interaction of antiprotons with nuclei is investigated in a model using the free space pN 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. By detecting a pion ejected from the annihilation zone in coincidence with the final A-1 system the the annihilation process can be localized spatially and used to to extract specific information on the nuclear wave function.
