The polarization buildup in a p-bar beam due to the interaction of stored antiprotons with polarized protons of a hydrogen target is considered. The corresponding cross section is calculated in the energy interval 20<T{sub lab}<100 MeV using the Paris nucleon-antinucleon optical potential. It follows from this estimate that, at realistic parameters of a storage ring and a target, the filtering mechanism can provide a noticeable polarization in a time comparable with the beam lifetime.
