Abstract

Neutron time-of-flight techniques and a liquid-helium polarized-neutron analyser were used to measure seven neutron polarization angular distributions for the 3H(d, n)4He reaction at deuteron energies from 1.0 to 5.0 MeV. Using Legendre polynomial expansions of σ(θ) and P(θ)σ(θ), values of P(θ) and P2(θ)σ(θ) were calculated, and a contour map of P(θ) was produced for the energy range 1.0 to 5.0 MeV. Various techniques used to measure the 3H(d, n)4He polarizations are discussed, and previous and present results are compared.
