Experimental data on the nuclear spin-isospin response in the quasifree region, measured with the charge-exchange reaction (d→,2p${[}^1$${\mathit{S}}_0$]) at Laboratoire National Saturne, are presented. The use of a tensor-polarized beam enables us to separate the tensor analyzing powers ${\mathit{T}}_{20}$ and ${\mathit{T}}_{22}$. The present publication is intended to serve as a compilation of the complete set of quasifree data with the (d→${,}^2$He) reaction at 1.6 GeV bombarding energy. Data for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ are compared to calculated cross sections and tensor-analyzing powers. The cross section in the high-energy end of the quasielastic peak is underestimated, whereas the polarization observables are reasonably well reproduced. The distortion effects are, however, found to be large, suggesting that the (d→${,}^2$He) reaction is not sensitive to spin correlations in the continuum.
