Abstract: A systematic analysis of the elastic scattering of deuterons by beryllium isotopes 7,9,10,11Be in the energy range Ed = 1 ÷ 28 MeV is performed. The energy-dependent potential for the d + 9Be system is built, which provides a good enough description of the experimental data, considering also changes of the diffractive scattering picture with energy increasing. A regular energy-dependent behavior and a regular target-dependent behavior of the differential cross sections of the deuteron scattering is demonstrated. Deviations from such a regular behavior is only observed in the experimental data for the d + 11Be elastic scattering at Ed = 5.6 MeV.

Keywords: elastic scattering, optical model, energy dependence.
