Polarization Transfer in the ReactionT(d,n)He4at 0° from 3.9 TO 15 MeV

Measurements of neutron polarization are reported for the reaction $\mathrm{T}\mathrm{}(d,n)\mathrm{}{}_{}{}^4{}_{}{}^{}\mathrm{He}$ at 0° in which the incident beam is polarized with quantization axis perpendicular to the direction of motion. The beam polarization was described by $p_3=p_{33}\approx 0.76$, while beam intensities varied from 10 to 40 nA. At $E_d=15\mathrm{}$ MeV the neutron polarization was measured to be +0.56±0.036 with respect to the quantization axis. At 3.9 MeV the polarization was zero, showing the influence of spin-flip interactions from the low-energy ${}_{}{}^4{}_{}{}^{}S_{\frac{3}{2}}^{}{}_{}{}^{}$ resonance. The measurements are related to polarization transfer and efficiency tensor functions for the reaction.
