Abstract
With the aim of clarifying roles of the 3NFs in nuclei experimental programs with the polarized deuteron beam at intermediate energies are in progress at RIKEN RI Beam Factory. As the first step, we have measured a complete set of deuteron analyzing powers in deuteron–proton elastic scattering at 250 and 294 MeV/nucleon. The obtained data are compared with the Faddeev calculations based on the modern nucleon–nucleon forces together with the Tucson–Melbourne’99, and UrbanaIX three nucleon forces.

Summary
The study of three nucleon forces (3NFs) is essentially important in clarifying nuclear phenomena. In addition to the first signals of the 3NF effects in the binding energies of the 3H and 3He, the necessity of 3NFs has been recently pointed out for descriptions of discrete states in higher mass nuclei [1]. Significance of 3NFs has been further supported by the equation of state of nuclear matter [2]. Three nucleon (3N) scattering at intermediate energies (E/A ∼ 200 MeV) is one attractive approach to investigate the dynamical aspects of 3NFs, such as momentum and/or spin dependences. With the aim of clarifying the role of the 3NFs in nuclei the experimental programs with polarized deuterons beams at intermediate energies are in progress at RIKEN RI Beam Factory (RIBF). We have measured a complete set of deuteron analyzing powers (iT11, T20, T21, T22) in deuteron– proton (d p) elastic scattering at 250 and 294 MeV/nucleon
