Antiproton-Deuteron Elastic Scattering between 1.60 and 2.00 GeV/c

We have studied antiproton-deuteron elastic scattering between 1.60 and 2.00 GeV/c incident momenta. The differential cross sections may be characterized by a very steep forward peak (with $b\sim 43$ ${\mathrm{GeV}}^{-2\mathrm{}}$) and a prominent break near $-t\sim 0.2$ ${\mathrm{GeV}}^2$. The results are used to test the validity of Glauber's multiple-scattering theory. Within the experimental range of measurements ($-t$ between 0.028 and 0.46 ${\mathrm{GeV}}^2$), the theory provides a good qualitative description of the data.
