Polynomial Expansions

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.

Bombarding Energy

The distributions in angle and energy for charged particles emitted from polycrystalline platinum bombarded with ions of hydrogen, sodium, potassium and some hydrocarbons, have been measured, in continuation of previous work (Cawthron, Cotterell & Oliphant 1969 a , b , parts I and II; 1970, part III) to lower energies. Composite spectra are presented, including ions of both signs. The flux of emitted charged particles, under hydrogen ion bombardment, is shown to contain approximately equal numbers of protons and H¯ ions, except at the lowest bombarding energies, where the latter apparently predominate. Scattering in all cases is shown to increase with bombarding energy over the range covered, the increase being near linear for hydrogen and very rapid for alkalimetal ions. In all cases the total emission of charged particles is very small at the lowest bombarding energies employed.
