The p-³He interaction for the polarized target is studied in the fixed centers approximation with all rescatterings included. Only the P₃₃ wave is taken for the pN 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 p⁺³He scattering at the lab energies T_p = 142, 180 and 256 MeV are calculated. The results are compared with experimental data.
