Abstract
Deuteron-nucleus elastic scattering at intermediate energies is analysed us ing a deuteron interaction obtained from the covariant folding of recent en ergy- and atomic-mass-number-dependent global Dirac-phenomenology nucleon-n ucleus potentials. The effects of allowing the nucleons in the deuteron to interact with the target with a variable energy, determined by their relati ve momentum, are studied for the first time. The inclusion of these effects in parameter-free calculations of cross section and polarization observabl es for deuteron elastic scattering on Mg-24, Ca-40 and Ni-58 improves the a greement with the data at deuteron energies of 400 and 700 MeV and is parti cularly strong at 400 MeV.
