Spin-dependent potentials for deuteron-nucleus scattering

Measurements of the cross section, the vector analyzing power, and the three tensor analyzing powers for deuteron elastic scattering from ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}$ at 5.5 MeV and from ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ at 9.0 MeV are presented. These measurements and additional measurements obtained from the literature are analyzed in terms of the optical model. The folding model is used to calculate the spin-dependent potentials from the known nucleon-nucleus potentials, and the central terms in the optical potential are determined empirically. Acceptable agreement is obtained for the cross section and vector analyzing power. The calculations reproduce the observed tensor analyzing powers for sub-Coulomb energies but not for energies above the Coulomb barrier.
