Neutron transmission spectra of a rotating crystal carry information about its lattice. The relationship between Bragg-dip positions in the spectra and the crystal lattice is investigated theoretically, and schemes for unambiguous determination of crystal orientation and lattice parameters are presented.

In order to maintain the heritage-listed Sydney Harbour Bridge, the steel surface must be regularly protected with a paint coating. Before applying a …

A new wide-aperture multi-element scintillation detector was commissioned at the high-resolution neutron Fourier diffractometer operating at the IBR-2 pulsed reactor. The performance of the diffractometer has improved significantly, and new experimental opportunities have emerged.

The first one-dimensional implementation of the Trench-MWPC technology has been carried out in a large (1.5 m radius and 160° angular coverage) curved 3He-based detector for the D20 high-resolution high-intensity neutron diffractometer at the Institut Laue–Langevin.

A straightforward method is presented for absolute intensity normalization of neutron scattering data from polycrystalline samples, using the intensity scale factor obtained from a Rietveld refinement.

The program 3DSOC provides a new way of extracting single-crystal substructure information from monochromatic neutron diffractometer data.

The results are presented of a high-pressure neutron powder diffraction study on lead cyanamide, carried out with the novel method of multidimensional Rietveld refinement. In addition to better resolution than the standard one-dimensional case, the results show the first evidence of changing C—N bond multiplicities as a function of pressure, numerically quantified from density functional theory calculations.

This paper demonstrates an event-mode imaging based neutron diffraction detector system that employs a scintillator screen, an image intensifier and a Timepix3-based camera. This highly configurable approach allows for large-solid-angle low-cost neutron diffraction setups with a performance comparable to that of the 3He detectors on a time-of-flight neutron diffraction beamline.

The magnetic structure of the intermetallic compound ErGa as a function of temperature has been determined using a combination of high-resolution neutron powder diffraction and 166Er Mössbauer spectroscopy. ErGa orders as a b-axis ferromagnet at 32 K and undergoes a spin-reorientation at 16 K to yield a canted ferromagnetic structure with the magnetic moments in the bc plane below 16 K.

Magnetic metal–organic frameworks are candidate materials for investigating two-dimensional phenomena. The magnetic structures of deuterated formate Co(DCOO)2·2D2O has been studied by neutron powder diffraction.

The magnetic and crystal structures of manganese and nickel monoxides have been analysed for possible multi-k solutions and compared with high-resolution neutron diffraction data.

Magnetic structures in R5Pt2In4 (R = Tb–Tm) are determined from neutron powder diffraction.

The crystal structure and surface layers of superprotonic conductor caesium hydrogen sulfate phosphate have been investigated by neutron diffraction and atomic force microscopy methods. Accurate data on their hydrogen bonding and surface characteristics have been obtained.
