Quasifree (d,2He) data

Experimental data on the nuclear spin-isospin response in the quasifree region, measured with the charge-exchange reaction (d,2p[1S0]) at Laboratoire National Saturne, are presented. The use of a tensor-polarized beam enables us to separate the tensor analyzing powers T20 and T22. The present publication is intended to serve as a compilation of the complete set of quasifree data with the (d,2He) reaction at 1.6 GeV bombarding energy. Data for C12 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,2He) reaction is not sensitive to spin correlations in the continuum.
