### Abstract

Antiproton scattering off $$^3\He$$ and $$^4\He$$ targets is considered at beam energies below 300 MeV within the Glauber-Sitenko approach, utilizing the $$\bar N N$$ amplitudes of the J\"ulich model as input. A good agreement with available data on differential $$\bar p ^4\He$$ cross sections and on $$\bar p ^3\He$$ and $$\pbar ^4\He$$ reaction cross sections is obtained. Predictions for polarized total $$\bar p ^3$$He cross sections are presented, calculated within the single-scattering approximation and including Coulomb-nuclear interference effects. The kinetics of the polarization buildup is discussed.
