The tensor A yy and vector A y analyzing powers in the inelastic scattering of deuterons with a momentum of 4.5 GeV/c on beryllium at an angle of ∼80 mr in the vicinity of baryonic resonances excitation have been measured. The A yy data being in good agreement with the previous results obtained at a zero angle demonstrate an approximate t scaling up to ∼ −0.9 (GeV/c)2. The results of the experiment are compared with the predictions of the multiple-scattering and ω-meson exchange models.
