The value of the deutron matter root-mean-square radius $r_{\rm m}=1.9580\left( 61\right)$\,fm and quadrupole moment $Q=0.2723(17)$ fm$^{2}$ that correspond to the experimental value of the deuteron effective radius of Borbély \textit{et al.} $ρ =1.727\left( 26\right) \,\,$fm, are obtained on the basis of correlation dependence between the deuteron matter root-mean-square radius $r_{\rm m}$\ and effective radius $ρ $ and also on the basis of the quadrupole moment $Q$\ dependence on the root-mean-square radius $r_{\rm m}$. The deuteron matter radius $r_{\rm m}$, structure radius $r_{\rm d}$ and charge radius $r_{\rm ch}$, as well as the quadrupole moment $Q$, are determined for modern experimental data on phase shifts of the GWU group and of the Nijmegen group. Phase shifts of the GWU group appear to be in better agreement with experimental characteristics of the deutron than phase shifts of the Nijmegen group.
