Tensor analyzing power measurement of ¹H(d, ²He)n reaction at 70 MeV

Tensor analyzing powers A_yy were measured for the ¹H(d, ²He)n reaction at E_d = 70 MeV. At forward angles, experimental data are reasonably reproduced by a PWIA calculation. This is inconsistent with the result reported on the transverse polarization coefficients K_y^y, at 0° of the same reaction with a proton beam, ²H(p, n)²He. This cannot be understood wholly within the frame-work of the impulse approximation. At backward angles, where the momentum transfer is large, PWIA predictions deviate far from the experimental data indicating a large contribution of the multiple scattering process.
