  In the framework of the light-front quantum theory developed by Karmanov et
al. an analysis of the experimental data on the tensor analyzing power of the
nuclear fragmentation of relativistic deuterons with the large transversal
momentum proton emission has been made. With the Karmanov's wave function taken
in system in which z-axis directed along the deuteron beam we have managed to
explain the existing data without invoking additional to nucleons degrees of
freedom.
