Three-nucleon interactions: Evidence from polarized pd elastic scattering

Journal Article (Journal Article)

Advances in precise computation of three-body reaction observables have spurred new interest in experimental measurements of proton deuteron elastic scattering, especially with regard to spin effects. Developments in spin-polarized internal targets for storage rings have permitted measurements of 197 MeV polarized protons scattering from vector polarized deuterons. This work presents measurements of the polarization observables Ay, iT11, and Cy,y in proton-deuteron elastic scattering. When compared to calculations with and without three-nucleon forces, the measurements indicate that three-nucleon forces make a significant contribution to the observables. This work indicates that three-body forces derived from static nuclear properties appear to be crucial to the description of dynamical properties.
