Spin dependence of the pbar-d and pbar-3He interactions
Abstract
Elastic scattering of antiprotons on deuteron and 3He targets is studied within the Glauber-Sitenko theory. In case of pbar-d scattering, the single- and double pbar-N scattering mechanisms and the full spin dependence of the elementary pbar-N scattering amplitudes are taken into account on the basis of an appropriately modified formalism developed for p-d scattering. Differential cross sections and analyzing powers are calculated for antiproton beam energies between 50 and 300 MeV, using the Nbar-N model of the Juelich group as input. Results for total polarized cross sections are obtained via the optical theorem. The efficiency of the polarization buildup for antiprotons in a storage ring is discussed.
