Modeling of the deuteron wave function in coordinate representation for the nucleon-nucleon potential Reid93 were performed. For this purpose, the asymptotics of the radial wave function near the origin of coordinates and at infinity are taken into account. The most simple and physical asymptotics were applied. In this case, the superfluous knots of both components of the deuteron wave function for the coordinate value r=0.301 fm were compensated. Taking into account the asymptotics of the wave function has little effect on the general behavior of the calculated polarization characteristics of t20 and Ауу. Particular points of the transmitted momentum have been identified, where the tensor deuteron polarization t20 and the tensor analyzing power Ауу show a clear difference.

The theoretical estimates of the A yy and A y values are compared with the experimental data for the reaction of (d,d') type on light nuclei: on hydrogen [23], carbon [23,28,29], beryllium [21,22,25].

Polarization observables of the A(d,d')X reactions have been calculated according to the received coefficients of the analytical form for deuteron wave function in coordinate space for the nucleon-nucleon Nijmegen group potentials (NijmI, NijmII, Nijm93). The obtained values of tensor A yy and vector A y analyzing powers have been compared with the published experimental data at t-scaling for the inelastic scattering of deuterons on hydrogen, carbon and beryllium. Theoretical values of tensor-tensor K yy and vector-vector K y polarization transfers have been also evaluated in the plane-wave impulse approximation.

The major goal of the upgraded Nuclotron facility is to obtain the information on the equation-ofstate for dense nuclear matter playing a key role in the understanding of the collapse supernovae and neutron stars stability. These studies can be performed either in heavy ion collisions or via the short-range few nucleon correlations in deuteron induced reactions. The obtained experimental results and future program with the use of polarized deuteron beam and the internal target station are discussed. The polarization studies for the NN, NA and dA reactions with the extracted deuteron beam at the BM@N setup are proposed. The further extension of the polarization program at BM@N is related with the study of the in-medium modification of the polarization for the strange and multi-strange baryons and the spin alignment for vector mesons decaying in hadronic modes.
