Antinucleon-nucleus interaction near threshold from the Paris $\bar NN$ potential
Abstract
A general algorithm for handling the energy dependence of hadron-nucleon amplitudes in the nuclear medium, consistently with their density dependence, has been recently applied to antikaons, eta mesons and pions interacting with nuclei. Here we apply this approach to antiprotons below threshold, analyzing experimental results for antiprotonic atoms across the periodic table. It is also applied to antiproton and antineutron interaction with nuclei up to 400 MeV/c, comparing with elastic scattering and annihilation cross sections. The underlying scattering amplitudes are derived from the Paris potential, including modifications in the medium. Emphasis is placed on the role of the -wave amplitudes with respect to the repulsive -wave amplitudes.
