Abstract
Elastic scattering of deuterons from $^{208}\mathrm{Pb}$ in the energy range ${\mathit{E}}_{\mathit{d}}$=9 to 79.2 MeV is analyzed using a dispersive optical model potential (OMP). In this analysis, a dispersion relation connects the volume integrals of the imaginary and the real parts of the OMP. Best-fit dispersive OMP parameters are obtained from fits to experimental cross-section and analyzing power data at one energy, and dispersive OMP parameters with a smooth energy dependence are determined from fits to the entire data set. Comparisons, showing fits of similar quality, of the predictions of the cross sections and analyzing powers given by the best-fit dispersive OMP and standard OMP are presented. Dispersive OMP parameters with a smooth energy dependence also give a good description of the experimental data.
