We studied the p̅ interactions with the nuclear medium within the 2009 version of the Paris N̅ N potential model. We constructed the p̅–nucleus optical potential using the Paris S - and P-wave p̅ N scattering amplitudes and treated their strong energy and density dependence self-consistently. We considereda phenomenological P-wave term as well. We calculated p̅ binding energies and widths of the p̅ bound in various nuclei. The P-wave potential has very small effect on the calculated p̅ binding energies, however, it reduces the corresponding widths noticeably. Moreover, the S -wave potential based on the Paris amplitudes supplemented by a phenomenological P-wave term yields the p̅ binding energies and widths in very good agreement with those obtained within the RMF model consistent with p̅-atom data.
