Abstract

Angular distributions of the neutron polarizations for the n₀ and n₁ groups from the ⁶Li(d, n) and ⁷Li(d, n) reactions were measured for deuteron energies from 2.5 to 3.7 MeV. Helium was used as a polarization analyzer and a spin precession solenoid was used to simulate interchange of the “side” detectors. The polarization distributions for the four groups studied have shapes that are very constant with energy over the energy range studied. The maximum absolute value of the measured polarizations is greater than about 0.40 for all except the ⁷Li(d, n₁) reaction. Distorted wave Born approximation calculations in which capture of the proton in the 1p shell with $j = 32$ was assumed, were made for the ⁶Li(d, n₁ and ⁷Li(d, n₀) reactions at 3.7 MeV. Using optical-model parameters that were obtained from published values, reasonable agreement with cross-section data was obtained and the predicted polarizations resembled the measured data somewhat.
