Abstract
The cross section, the deuteron vector A(y)(d) and tensor analyzing powers A(ij), the polarization transfer coefficients K-ij(y'), and the induced pol arization P-y' were measured for the dp elastic scattering at 270 MeV. The cross section and A(y)(d) are well reproduced by Faddeev calculations with modern data-equivalent nucleon-nucleon forces plus the Tucson-Melbourne thr ee-nucleon force. In contrast, A(ij), K-ij(y'), or P-y' are not described b y such calculations. These facts indicate the deficiencies in the spin depe ndence of the Tucson-Melbourne force and call for extended three-nucleon fo rce models.
