Abstract
The data on the vector Ay and tensor Ayy, Axx, Axz analyzing powers for the
dd → 3Hp and dd → 3Hen reactions at Ed=200 and 270 MeV are presented. The
tensor analyzing powers for these reactions demonstrate the sensitivity to the 3H, 3He and deuteron spin structure. The essential disagreements between the experimental
results and the theoretical calculations within the framework of the onenucleon
exchange model are observed. Obtained experimental data are important
for the preparation of the experiments at the LHEP-JINR Nuclotron-M at higher
energies. It is planned to obtain new experimental data on the polarization observables
for the p(d, p)d, 3He(d, p) 4He and d(d, p) 3H reactions at intermediate and
high energies. These data will ensure new information on the spin structure of light
nuclei at the short internucleonic distances, where the relativistic effects and the
three-nucleon forces play an important role.
At the present time, there is a great deal of interest in understanding the short-range
spin structure of deuteron and other light nuclei, as 3 H and 3 He. They represent an
important testing ground for models of the NN interaction and for studies of the manybody
aspects of the strong interaction in nuclei. In addition, 3 H and 3 He are the simplest
systems in which the effects of possible three-body nuclear forces can be explored.
The essential amount of the experimental data sensitive to the structure of light nuclei,
have been accumulated at several last decades [1], [2]. Large discrepancies between the
Nd data and theoretical predictions based on exact solution of the Faddeev equations
