The differential cross sections of the elastic Nd scattering at the energy below 150 MeV can be well reproduced by introducing 3NF in the Faddeev calculations based on modern nucleon-nucleon (NN) interactions. On the other hand, some spin-observables, and the differential cross sections of Nd elastic and inelastic scatterings at over 250 MeV show large discrepancies between the data and the Faddeev calculations with 3NF. It indicates the presence of the missing features of the three nucleon systems. For the systematic study about these large discrepancies at higher energy regions, we measured the differential cross sections and the vector analyzing power for the inclusive and exclusive breakup reaction at 170 and 250 MeV. The experiments were carried out at RCNP. The data were compared with the results of the Faddeev calculations with and without the 3NF.
