摘要：

The polarization buildup in a pp beam which is due to the interaction of stored antiprotons with polarized protons of a hydrogen target is considered. The corresponding cross section is calculated using the Paris nucleon-antinucleon optical potential in the energy interval 20 < T-tab < 100 MeV. 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.
