We performed calculations of (p) over bar -nuclear quasi-bound states using an optical potential derived from the 2009 version of the Paris (N) over barN potential model. Self-consistent treatment of strong energy dependence of the considered S-and P-wave (p) over barN scattering amplitudes is essential for proper evaluation of (p) over bar binding energies and widths. The P-wave potential has very small effect on the calculated (p) over bar binding energies, however, it reduces the corresponding widths in large measure. The Paris S-wave potential supplemented by a phenomenological P-wave term yields the (p) over bar binding energies and widths very close to those obtained within the RMF model consistent with (p) over bar -atom data.
