zeolite-water systems, neutron powder diffraction measurements were performed on D2B on faujasite NaX loaded with D 2 O. These were combined with diffuse reflectance infrared fourier transform spectroscopic

IN5 choppers are large (Ø 75 or 69 cm) and thin disks (50 to 1 mm) coated with gadolinium oxide (Gd 2 O 3 ) rotating at high speed (up to 17000 rpm). Thin implied advanced aluminum metalurgy, magnetic bearings

The diffusion of oxygen in silicon single-crystals The small-angle neutron-scattering from SiO 2 precipitates in a single crystal of silicon which has been heat treated for 500 hours at 600°C; the neutron ... neutron beam was incident along a <100> direction. The central cross arises from the cushion shaped SiO 2 precipitates lying on (100) planes ...

moment The cerium magnetic form factor and diffuse polarization in CeRh 3 B 2 as functions of temperature In the compound CeRh 3 B 2 , a rather special polarization of the conduction electrons along the c-chains ... Thermal variation of the magnetization of CeRh3B2The data at T = 150 K were obtained in a different magnetic field, H = 9 T instead of ...

has been integrated vertically, therefore the x-axis corresponds to 2 theta, and the y-axis corresponds to the neutron wavelength (~2 - 20 Å). The reflected neutrons show a number of off-specular diffraction ... chemical properties essentially remain unchanged. An important example is that of 1 H (b = —3.74 fm) and 2 H ( = 6.67 fm). There is ...

working on a one-dimensional antiferromagnetic material with particular properties: BACOVO (BaCo 2 V 2 O 8 ). “We performed various experiments on BACOVO, an oxide characterised by its helical structure

Its reflectivity is particularly high at wavelengths about 1.7 Å using the (400) reflection and at 2.5 Å using the (311) reflection.

Anode wires, crimped with small copper tubes, are connected to the 32-pins feedthroughs ... workshop on Position Sensitive Neutron Detectors) took place at FZJ from the 15th to the 17th May. 2 detector meetings followed it at the same ...

replacement of the H1-H2 beam tube and in-pile neutron guides that allow the extraction and transport of thermal and cold neutrons to the instruments in the ILL7 guide hall. To replace the H1-H2 beam tube, a huge ... operation in itself, which gave the opportunity to modernise and renew infrastructure such as the H1-H2 pool at level C, which ...

the orientation of the crystal lattice planes to the diffraction position. Finally the fourth circle 2θ, rotates the detector to the diffracted beam. The closed Eulerian Cradle of D9 is stout enough to
