We constructed the p- -nucleus optical potential using the Paris S - and P-wave p- N scattering amplitudes and treated their strong energy and density dependence self-consistently. We considered a phenomenological P-wave term as well. We calculated p- binding energies and widths of the p- bound in various nuclei. The P-wave potential has very small effect on the calculated p- 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 p- binding energies and widths in very good agreement with those obtained within the RMF model consistent with p- -atom data.
