[en] the δS=1, δT=0 transitions were studied by performing inelastic scattering of polarized deuterons on several nuclei. Inelastic cross sections, vector A_y and tensor A_yy values were measured at forward angles for different states in C12, Mg24, and Ca40 with 400 MeV polarized deuterons. The shapes of the angular distribution are characteristic of the δL-transfer. The analyzing powers A_y at forward angles is characteristic of the δS=0 or 1 transfer. As in (p,p') inelastic scattering, the energy of the 200 MeV/nucleon favors the excitation of δS=1 transitions relative to the δS=0 ones. The similarity between these (d,d') results and the (p,p') ones at 200 MeV indicates that a microscopic description of the (d bar, d') scattering in terms of N-N interaction can be undertaken
