Abstract.

We have measured angular distributions of the differential cross-section, the analyzingpower and all of the spin transfer coefficients K y y, K x x, K z x, K x z, and K z z for the pd elastic scattering at 250 MeV. These are the first measurements of a complete set of proton polarization observables for pd elastic scattering at intermediate energies. The present data are compared with theoretical predictions based on exact solutions of the three-nucleon Faddeev equations and modern realistic nucleon-nucleon potentials combined with three-nucleon forces (3NF), namely the Tucson-Melbourne (TM) 2\(\pi\)-exchange model, a modification thereof (TM’) closer to chiral symmetry, and the Urbana IX model.
