Design study of a time of flight small-angle diffractometer for a pulsed neutron source

Description: The design study for a neutron SAS instrument at Argonne's proposed Intense Pulsed Neutron Source (peak thermal neutron flux 10/sup 16/ n/cm/sup 2/-sec) indicates that an effective high-resolution TOF SAS diffractometer can be constructed. The design features include a converging slit collimator, provision for 5 x 5 cm/sup 2/ sample cross sectional area, and a 1 x 1 m/sup 2/, two-dimensional detector. The fractional wavelength resolution of the instrument is negligibly small for all wavelengths… more

Lattice shear distortions in fluorite structure oxides

Description: Crystallographic shear distortions have been observed in fluorite structure, single crystals of UO/sub 2/ and Zr(Ca)O/sub 2//sub-x/ by neutron-diffraction techniques. These distortions localize on the oxygen sublattice and do not require the presence of an external strain. The internal rearrangement mode in UO/sub 2/ is a transverse, zone boundary q vector = 2..pi../a (0.5, 0.0) deformation with amplitude 0.014 A. In Zr(Ca)O/sub 2-x/, the mode is a longitudinal, q vector = 2-/a (0,0,0.5) deform… more
