Abstract
The π3He interaction for the polarized target is studied in the fixed-centers approximation with all rescatterings included. Only the P33 wave is taken for the πN interaction. The nuclear wave function is taken either as a sum of Gaussians or as a Faddeev wave function in the s-wave approximation. The asymmetries for elastic π + 3He scattering at the lab energies Tπ =142, 180 and 256 MeV are calculated. The results are compared with experimental data.
