“…The measurements of the tensor analyzing powers [20] have shown their sensitivity to the D-state component in 3 He. Recently the vector A y and tensor A yy , A xx analyzing powers have been measured at KV I at 55, 66.5 and 90 MeV/nucleon [21]. The data are in a good agreement with the results of Faddeev calculations obtained by the Bochum-Cracow [22] and Hannover groups [23], which have shown the effect of 3N F to be small at these energies.…”

“…However, the deviation of the experimental data from the ONE calculations at large angles can be due to not only the nonadequate description of the short range 3 He spin structure, but also to the influence of the mechanisms additional to ONE. The measurements of the polarization observables in the dd → 3 Hen process can provide independent information on the 3 He spin structure with respect to the data for the 3 He(p, pN ) [19] and dp → 3 Heγ [21,24] reactions, where the rescattering and meson-exchange current effects play an important role and mask the structure of 3 He.…”

Abstract. The data on the tensor Ayy, Axx, Axz and vector Ay analyzing powers in the dd → 3 Hen obtained at T d = 270 MeV in the angular range 0• -110• in the c.m. are presented. The observed negative sign of the tensor analyzing powers Ayy, Axx and Axz at small angles clearly demonstrate the sensitivity to the ratio of the D and S wave component of the 3 He wave function. However, the one-nucleon exchange calculations by using the standard 3 He wave functions have failed to reproduce the strong variation of the tensor analyzing powers as a function of the angle in the c.m.PACS. 24.70.+s Polarization phenomena in reactions -25.10.+s Nuclear reactions involving few-nucleon system -21.45.+v Few-body systems

The nucleon-deuteron radiative capture process is investigated using the chiral nuclear potentials and the electromagnetic currents developed by the Bochum-Bonn group. While the strong interaction is taken up to the next-to-next-to-leading order, the electromagnetic current consists of a single nucleon current, the leading one-pion exchange one and is supplemented by contributions from the long-range two-pion exchange current at next-to-leading-order. The theoretical predictions for the cross sections as well as analyzing powers show strong dependence on the values of regularization parameters. Only small effects of the three-nucleon force and the long-range two-pion exchange current are observed. The dependence on the choice of regularization parameters results in a big theoretical uncertainty and clearly points to the necessity to include corrections from higher orders of the chiral expansion both for the nuclear forces and currents.
