Abstract
Precise data on cross sections, analyzing powers and polarization transfer coefficients are measured for the dp elastic scattering at 270 MeV (135 MeV/nucleon) and compared to Faddeev calculations assuming the nd scattering with modern nucleon-nucleon (NN) forces including the 2{pi} exchange Tucson-Melbourne (TM) three-nucleon (3N) force. Excellent fits are obtained for the cross sections and vector analyzing powers when the 3N force is included, while the fits are deteriorated for the tensor analyzing powers if the 3N force is included. A moderate fit is obtained for the polarization transfer coefficients. Based on theses results, one can conclude that the size of amplitudes of the TM-3N force may be adequate but the spin dependent part may be deficient. The cross sections and the vector analyzing powers for the nd elastic scattering at 250 MeV are measured for the first time. Backward cross sections are underestimated by the NN+3N force Faddeev calculations. This difference might be attributed to relativistic effects.
