Neutron time-of-flight techniques have been used to measure [Formula: see text] polarization angular distributions for several deuteron energies from 0.87 to 5.00 MeV. Liquid helium served as the polarized neutron analyzer. From Legendre polynomial expansions of σ(Θ) and P(Θ)σ(Θ), contour maps of P(Θ) and P2(Θ)σ(Θ) have been produced for the energy range 0.87 to 5.00 MeV. Comparison with previous results and measurement techniques are discussed. Nucleon polarizations from the charge symmetric reactions [Formula: see text] and [Formula: see text] are compared.

Complete Specification

The angular distribution of α-particles from Li6(d,α)He4 has been investigated for deuteron energies between 200 keV. and 1 MeV. The distribution may be represented by the expression������������������ N(θ)=N(90�)[1+A(E) cos2θ], where A(E) is a function of deuteron energy. The variation of A(E) with energy is due to the increasing penetration of the potential barrier by d deuterons. The angular distributions of the two groups of protons from Li6(d,p)Li7*, Li7 have been investigated in the same energy range. The distributions are complex and require d deuterons for their complete specification in the form �������������� N(θ) = a0P0 + a1P1 = a2P2 = a3P3 = a4P4where Pn is the Legendre polynomial of order n. The results appear to resolve some differences apparent in earlier work. There is no evidence that the short range proton distribution is more complex than that of the long range group.
