Abstract

It is shown that the vector and tensor analyzing powers $A_y$ , $A_{yy}$ and also double spin correlation coefficients $C_{y,y}$ , $C_{y y,y}$ of the reaction $dd\to n+p+d$ in impulse approximation are linearly connected to corresponding observables of the $pd$ - elastic scattering. Obtained relations are necessary for motivation of the polarization experiments for the first phase of the SPD NICA project and for analysis of expected data.
