TITLE=/Pion-deuteron elastic scattering at large angles for momenta
from 460 to 1160 MeV/c/;
PURPOSE=/The differential cross section for pi- - d elastic scattering
at c.m. pion angles 91 deg., 104 deg., 123 deg., 136 deg., and
155 deg. has been measured for pion momenta between 460 and
1160 MeV/c with the finest momentum steps so far employed./;
