Abstract:	The investigation of the spin structure of d, ³H, and ³He has been performed at the RIKEN acceleration research facility and VBLHE. Vector A _y and tensor A _yy, A _xx, A _xz analyzing powers for $\vec d$ d → ³Hen and $\vec d$ d → ³Hp are presented at 270 MeV. Themirror channels (³Hen and ³Hp) are comparedto each other in order to find possible manifestation of charge-symmetry breaking. The preliminary results on the polarization observables for $\vec d$ d → ³Hp at 200MeV are also presented. The obtained data are compared with one-nucleon-exchange calculations.As a byproduct, $\vec d$ d → pX and $\vec d$ ¹²C → pX breakup reactions are investigated at 140, 200, and 270MeV. The experimental data on $\vec d$ p elastic scattering were obtained at 270, 880, and 2000 MeV at the Nuclotron. The polarization of the deuteron beam was measured at 270 MeV at the internal target station. The preliminary data on the vector A _y and tensor A _yy, A _xx analyzing powers for the $\vec d$ p elastic scattering at 880 MeV are presented. The calculations on A _y, A _yy, and A _xx analyzing powers for the $\vec d$ p elastic scattering at 880 MeV were performed in the framework of the multiple-scattering model. The text was submitted by the authors in English.
