Popis: The Coulomb-modified Faddeev equations were solved in momentum space for different separable potential models at {ital E}{sub lab}{sup {ital p}}=2.5 and 3.0 MeV. The best agreement with available experimental data of zero- and first-order spin polarization observables was achieved by employing a separable approximation of the Paris potential in the calculation. These results, together with predictions of second-order {ital p}-{ital d} polarizations, demonstrate the necessity of a correct treatment of three-body Coulomb corrections. Moreover, no indication of model sensitivity is found in our results. Three-nucleon phase shift parameters are given and the validity of a simple approximate two-body description of the three-body Coulomb corrections is discussed.
