Optical model potentials for deuteron scattering off Mg 24, Si 28, Ni 58, Zr 90, Sn 116, and Pb 208 at ≈100 MeV/nucleon

Angular distributions of the elastic and inelastic deuteron-nucleus scattering off Mg24, Si28, Ni58, Zr90, Sn116, and Pb208 have been measured at a beam energy of 98 MeV/nucleon, with the goal of constraining the deuteron optical potential in this kinematical regime and to extract the reduced transition probabilities for the ground-state transitions to low-lying excited states of these nuclei. Two potential models were used in the analysis of the measured (d,d) and (d,d′) data within the optical model and the distorted-wave Born approximation: the phenomenological optical model potential associated with the collective model of nuclear scattering, and the semimicroscopic double-folding model of the deuteron-nucleus potential based on a realistic density-dependent M3Y interaction. The deuteron optical potential and inelastic (d,d′) scattering form factors were calculated using these two potential models, allowing for a direct comparison between the potential models as well as the validation of the deduced Eλ transition rates.
