## Abstract

Deuteron-nucleus spin-dependent interactions are investigated in elastic scattering at intermediate energies. Spin-space tensor amplitudes which characterize spin-dependent interactions are introduced by the invariant-amplitude method so that effects of T_{R}- and T_{L}-type tensor interactions are described separately. Through these amplitudes, numerical calculations based on the folding model clarify that the spin-orbit interactions produce T_{L}-tensor like effects on the scattering amplitude as the higher-order effect and the virtual breakup contribution is only a minor part of this effect in most angles. An additional T_{L}-type tensor interaction, phenomenologically introduced, is found to improve the fit to the experimental data of A_{yy} considerably and A_{y} in less magnitude. The origin of this interaction is discussed. The theoretical prediction is made of which observables enhance the effect of a particular spin-dependent interaction.
