    "abstract": "Polarized antiprotons can be produced in a storage ring by spin--dependent\ninteraction in a purely electron--polarized hydrogen gas target. The polarizing\nprocess is based on spin transfer from the polarized electrons of the target\natoms to the orbiting antiprotons. After spin filtering for about two beam\nlifetimes at energies $T\\approx 40-170$ MeV using a dedicated large acceptance\nring, the antiproton beam polarization would reach $P=0.2-0.4$. Polarized\nantiprotons would open new and unique research opportunities for spin--physics\nexperiments in $\\bar{p}p$ interactions.",
