    "abstract": "A polarized, internal electron target gradually polarizes a proton beam in a\nstorage ring. Here, we derive the spin-transfer cross section for $\\vec\ne\\,(p,\\vec p\\, )e$\\ scattering. A recent measurement of the polarizing effect\nof a polarized atomic hydrogen target is explained when the effect of the\natomic electrons is included. We also consider the interaction of a stored beam\nwith a pure electron target which can be realized either by a comoving electron\nbeam or by trapping of electrons in a potential well. In the future, this could\nprovide a practical way to polarize antiprotons.",
