The tensor analyzing power T2p for the reaction d + '2C p(0 ) + 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 T2o have a tendency to approach the value ( -0.3) obtained by the calculation based on the reduced nuclear amplitude method in which the quark degrees of freedom are taken into account.
