Abstract

Elastic scattering of deuterons by nuclei at intermediate energies is investigated by the sudden approximation. Scattering amplitudes of the deuteron are described in terms of those of the constituent nucleons. They consist of the amplitude of nucleon-nucleus single collision and that of double collision. The neglect of the latter explains similarity relations between the deuteron observables and the proton ones, which are found in experimental data. Cross sections and vector analyzing powers calculated with the single-collision terms successfully reproduce the measured ones for 16O, 40Ca and 58Ni targets in the energy region, Ed = 200 ~ 700 MeV. Scattering of 6Li by 58Ni is investigated in a similar way assuming the d + α cluster model for 6Li.
