  Polarization correlation coefficients have been measured atRIKEN for the \vec
3He(\vec d,p)4He reaction at intermediate energies. We propose a model for the
(\vec d, p) reaction mechanism using the pd elastic scattering amplitude which
is rigorously determined by a Faddeev calculation and using modern NN forces.
Our theoretical predictions for deuteron polarization observables A_y, A_{yy},
A_{xx} and A_{xz} at E_d=140, 200 and 270 MeV agree qualitatively in shape with
the experimental data for the reaction 3He(\vec d,p)4He.
