Abstract
The tensor analyzing power ${T}_{20}$ for the reaction ${d}^{\ensuremath{\uparrow}}{+}^{12}\mathrm{C}\ensuremath{\rightarrow}p(0\ifmmode^\circ\else\textdegree\fi{})+X$ has been measured in the region of proton internal momenta $k$ in light-cone dynamics up to 1 GeV/ $c$. Measurements have been carried out at Dubna Synchrophasotron with polarized deuteron beam at deuteron momenta up to 9 GeV/ $c$. When $k$ increases the experimental values of ${T}_{20}$ have a tendency to approach the value ( $\ensuremath{-}$0.3) obtained by the calculation based on the reduced nuclear amplitude method in which the quark degrees of freedom are taken into account.
