The angular dependence of the tensor A{sub yy} and vector A{sub y} analyzing powers in the inelastic scattering of deuterons with a momentum of 9.0 GeV/c on hydrogen and carbon has been measured. The range of measurements corresponds to the baryonic resonance excitation with masses of {approx}2.2-2.6 GeV/c{sup 2}. The A{sub yy} data, being in good agreement with the previous results, demonstrate an approximate t scaling up to -1.5 (GeV/c){sup 2}. The large values of A{sub y} show a significant role of the spin-dependent part of the elementary amplitude of the NN {sup {yields}} NN* reaction. The results of the experiment are compared with model predictions of the plane-wave impulse approximation.
