Microscopic relativistic model for deuteron-nucleus scattering
- Centro de Fisica Nuclear da Universidade de Lisboa, Av. Gama Pinto, 2, 1699 Lisboa (Portugal)
The relativistic deuteron structure described by the Bethe-Salpeter formalism is used to obtain the deuteron-nucleus interaction from the covariant convolution of Dirac-phenomenology nucleon-nucleus potentials. Multiple scattering contributions to deuteron-nucleus scattering are taken into account by the positive energy subtracted impulse approximation which results from an analysis of the role played by the relativistic degrees of freedom. A detailed comparison of calculations with deuteron-nucleus elastic scattering data at intermediate energies, including polarization observables, is presented. It is shown that good agreement with the data is obtained when the full spin structure of the interaction that results from the relativistic model is included in the calculations. {copyright} {ital 1996 The American Physical Society.}
