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.
