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 TR- and TL-type tensor interactions are described separately. Through these amplitudes, numerical calculations based on the folding model clarify that the spin-orbit interactions produce TL-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 TL-type tensor interaction, phenomenologically introduced, is found to improve the fit to the experimental data of Ayy considerably and Ay 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.
