Neutron Diffraction with the Metallic Glass Ni₃₁Dy₆₉ ( + 10 a/o D) Using Isotopic Substitution

Abstract

By neutron diffraction using the method of isotopic substitution with the amorphous alloy Ni 31 Dy 69 the partial structure factors S NiNi , S DyDy and S NiDy were obtained, furthermore with the same specimen containing 10 a/o deuterium a partial structure factor S DD resulted. For the evaluation of S DD it was necessary to perform the neutron diffraction experiment with an alloy whose both components were zero scattering isotopic mixtures of Ni or Dy, respectively.
