Abstract
We compare precise analyzing power measurements for p+d elastic scattering between 70 and 200 MeV proton laboratory energy with three-body Faddeev cal culations. Using the CD-Bonn nucleon-nucleon force alone leads to an overpr ediction of the data at higher energies, suggesting that three-body (3NF) f orces may be important. The 2 pi-exchange Tuscon-Melbourne 3NF model, adjus ted to match the triton binding energy, leads to a better shape for the exc itation function but gives too large of an effect.
