  • Description: Spin-dependent total ($) over bar pd cross sections are considered using the optical theorem. For this aim the full spin dependence of the forward ($) over bar pd elastic scattering amplitude is considered in a model independent way. The single-scattering approximation is used to relate this amplitude to the elementary amplitudes of ($) over bar pp and ($) over bar pn scattering and the deuteron form factor. A formalism allowing to take into account Coulomb-nuclear interference effects in polarized ($) over bar pd cross sections is developed. Numerical calculations for the polarized total ($) over bar pd cross sections are performed at beam energies 20-300 MeV using the ($) over bar NN interaction models developed by the Julich group. Double-scattering effects are estimated within the Glauber approach and found to be in the order of 10-20%. Existing experimental data on differential ($) over bar pd cross sections are in good agreement with the performed Glauber calculations. It is found that for the used ($) over bar NN models the total longitudinal and transversal ($) over bar pd cross sections are comparable in absolute value to those for ($) over bar pd scattering.
