Abstract
Developments in spin-polarized internal targets for storage rings have perm itted measurements of 197 MeV polarized protons scattering from vector pola rized deuterons. This work presents measurements of the polarization observ ables A(gamma), iT(11), and C-gamma,C-gamma in proton-deuteron elastic scat tering. When compared to calculations with and without three-nucleon forces , the measurements provide further evidence that three-nucleon forces make a contribution to the observables. This work indicates that three-body forc es derived from static nuclear properties appear to be crucial to the descr iption of dynamical properties.
