Status of the investigation of the spin structure of d, {sup 3}H, and {sup 3}He at VBLHE using polarized and unpolarized deuteron beam

The investigation of the spin structure of d, {sup 3}H, and {sup 3}He has been performed at the RIKEN acceleration research facility and VBLHE. Vector A{sub y} and tensor A{sub yy}, A{sub xx}, A{sub xz} analyzing powers for d-bar-vector d {yields} {sup 3}Hen and d-bar-vector d {yields} {sup 3}Hp are presented at 270 MeV. The mirror channels ({sup 3}Hen and {sup 3}Hp) are compared to each other in order to find possible manifestation of charge-symmetry breaking. The preliminary results on the polarization observables for d-bar-vector d {yields} {sup 3}Hp at 200MeV are also presented. The obtained data are compared with one-nucleon-exchange calculations. As a byproduct, d-bar-vector d {yields} pX and d-bar-vector {yields} {sup 12}C {yields} pX breakup reactions are investigated at 140, 200, and 270MeV. The experimental data on d-bar-vector 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{sub y} and tensor A{sub yy}, A{sub xx} analyzing powers for the d-bar-vector p elastic scattering at 880 MeV are presented. The calculations on A{sub y}, A{sub yy}, and A{sub xx} analyzing powers for the d-bar-vector p elastic scattering at 880 MeV were performed in the framework of the multiple-scattering model.
