Elastic scattering of antiprotons on deuteron and 3He targets is studied within the Glauber-Sitenko theory. In case of antip-d scattering single- and double pbar N scattering mechanisms and the full spin dependence of the elementary pbar N amplitudes are taken into account on the basis of an properly modified formalism developed for pd-scattering . Predictions for differential cross sections and the spin observables $A_y^d$, $A_y^{\bar p}$, $A_{xx}$, $A_{yy}$ are presented for anti-proton beam energies between 50 and 300 MeV, using amplitudes generated from the $\bar N N$ interaction model developed by the J\"ulich group. Total polarized cross sections are calculated utilizing the optical theorem. The efficiency of the polarization buildup for anti-protons in a storage ring is investigated.
