The elastic scattering of 56 MeV polarized deuterons over a wide mass region has been investigated. The target nuclei were 16O, 24Mg, 28Si, 32S, 40Ar, 40, 44Ca, 54Fe, 58, 60, 64Ni, 90Zr, 118Sn and 208Pb. Angular distributions of the cross section and vector analyzing power Ay have been measured for all target nuclei. The tensor analyzing power Ayy has also been studied, except for 24Mg and 28Si. The optical-model parameters were derived from an analysis including no tensor potentials. Volume integrals for the real and imaginary parts of the central potential and the spin-orbit interaction were calculated and compared with the folding-model predictions. The effect of a complex TR potential was studied. It was found that the real part of the TR potential tends to be zero for all the nuclei studied and the inclusion of the imaginary part improves the fit to the tensor analyzing power.
