We calculate the pion-deuteron elastic scattering at E/sub ..pi../= 142 MeV using nonrelativistic three-body equations in which relativistic kinematics are retained only for the pion. The NN tensor force is taken into account, and, for the first time, all S and P ..pi..N partial waves are included in an axact way. The coupling between l = J +- 1..pi..d channels is found to be not negligible, and we establish the large interference effects of all other than P/sub 33/..pi..N channels leading to a rather good description of the experimental data E/sub ..pi../= 142 MeV.
