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 72d scattering with modern nucleon-nucleon (NN) forces including the 2 pi exchange Tucson- Melbourne (TM) three-nucleon (3N) force. Excellent fits are obtained for th e cross sections and vector analyzing powers when the 3N force is included, while the fits are deteriorated for the tenser 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;a mplitudes of the TM-3N force may be adequate but the spin dependent part ma y be deficient. The cross sections and the vector analyzing powers for the nd elastic scatt ering at 250 MeV are measured for the first time. Backward cross sections a re underestimated by the NN+3N force Faddeev calculations. This difference might be attributed to relativistic effects.
