Spin-dependent pbar-d cross sections at low and intermediate energies

Abstract

Antiproton-deuteron ($\bar{p}d$) scattering is calculated at beam energies below 300 MeV within the Glauber approach, utilizing the amplitudes of the Jülich $\bar{N}N$ models. A good agreement is obtained with available experimental data on upolarized differential and integrated $\bar{p}d$ cross sections. Predictions for polarized total $\bar{p}d$ cross sections are presented, obtained within the single scattering approximation including Coulomb-nuclear interference effects. It is found that the total longitudinal and transversal $\bar{p}d$ cross sections are comparable in absolute value to those for $\bar{p}p$ scattering. The kinetics of polarization buildup is considered.
