Calculations of antiproton nucleus quasi-bound states using the Paris (N)over-barN potential

Original language description

An optical potential constructed using the (p) over barN scattering amplitudes derived from the 2009 version of the Paris (N) over barN potential is applied in calculations of (p) over bar quasi-bound states in selected nuclei across the periodic table. A proper self-consistent procedure for treating energy dependence of the amplitudes in a nucleus appears crucial for evaluating (p) over bar binding energies and widths. Particular attention is paid to the role of P-wave amplitudes. While the P-wave potential nearly does not affect calculated (p) over bar binding energies, it reduces considerably the corresponding widths. The Paris S-wave potential supplemented by a phenomenological P-wave term yields in dynamical calculations (p) over bar binding energies B-(p) over bar approximate to 200 MeV and widths Gamma((p) over bar) similar to 200-230 MeV, which is very close to the values obtained within the RMF model consistent with (p) over bar -atom data.
