STUDY OF THE ELASTIC-SCATTERING OF POLARIZED DEUTERONS FROM NI-60 AND ZR-90 NUCLEI

Five quantities, σ0, iT11, T20, T21 and T22, have been measured for the elastic (d, d) scattering from 60Ni at 9 and 12 MeV and from 90Zr at 10, 11 and 12 MeV over a wide angular range. Excitation functions for σ0 and T20 have been also measured at an angle of 175°(lab) in the approximate energy range of 6-13 MeV for both target isotopes. The experimental results, together with similar data published earlier for 15 MeV have now been analysed using the optical model with the complex central, spin-orbit and tensor TR potentials. Excellent fits are obtained for the angular distributions for all five measured quantities. The main features of the excitation functions are also well reproduced. Five of the optical-model parameters can be fixed. Three other parameters can be constrained by simple mass dependence functions. Further evidence for the presence of an imaginary component of the spin-orbit potential is supplied by the analysis of the present data. © 1979.
