Pion-Deuteron Elastic Scattering at Large Angles for Momenta from 460 to 1160 MeV/c

Abstract
The differential cross section for πd elastic scattering at c.m. pion angles 91°, 104°, 123°, 136°, and 155° has been measured for pion momenta between 460 and 1160 MeV/c with the finest momentum steps so far employed. A pronounced dip-bump structure around 700 MeV/c observed previously at 172° is confirmed at other angles, while the dip around 1000 MeV/c is found to degrade rapidly as the angle decreases. The angular distribution at large angles (> 90°) shows rather drastic changes at these momenta.
