minimize neutron loss at every step [ 2 ]. This places it in the category of “high density” UCN sources, in contrast to “high-flux” sources such as the ILL’s PF2 that have served the user community with ... lost within single scattering events [ 3 ].

Typical diffraction patterns The graph shows the diffraction patterns for H 2 O and D 2 O as measured on D4. After Fourier transformation such diffraction patterns provide information about the spatial

4 thin anodes per detection cell). The detection plates have each 32 cells of 2.568 mm (0.1˚) each, covering in total 3.2˚. The current PSD covers 153.6˚, with 48 plates mounted in a curved aluminium housing ... s response, a very high stability and the possibility of very high counting rates.

hydrogen is moved from the catalytic water, C2, and O2, and to O1 and C1, as a metal ion moves towards the aldehyde terminus of the linear sugar to bind to O1 and O2. These results have led to new suggestions ... XI-apo hydrogen bonded to three active site residues Glu181, Glu217 and Asp245 of xylose isomerase. The 2Fo-Fcneutron scattering d ...

the four magnetic moments in each tetrahedron must point inward and the two others outward. This “2 in-2 out” local constraint can be achieved by a number of ways that grows exponentially with the number ... higher-order multipolar moments. This was theoretically suggested to be the case in cerium stannate (Ce 2 Sn 2 O 7 ), where the single-ion ...
