Conference paper (peer-reviewed)abstract
- A new program of Compton scattering on deuterium is under way at the tagged-photon facility at MAX-Lab in Lund, Sweden. We will measure differential cross sections between 60A degrees and 150A degrees over the photon energy range 60-115 MeV in 5 MeV steps, with the ultimate goal of obtaining new precision information on the electric and magnetic polarizabilities of the neutron.

The structure of superconducting RbOs2O6 between 2 K and 300 K
- 2007
-
In: Journal of Materials Chemistry. - : Royal Society of Chemistry (RSC). ; 17:2, s. 160-163
-
Journal article (peer-reviewed)abstract
- The structure of RbOs2O6 can be described fully in the Fd (3) over barm space group between 2 and 298 K and large thermal displacement factors associated with the Rb ion are probably typical of this structure type and the site occupied.

Hydration, Structure, and Superconductivity of KOs2O6·nH2O
- 2008
-
In: Chemistry of Materials. - : American Chemical Society (ACS). - 0897-4756 .- 1520-5002. ; 20:4, s. 1652-1659
-
Journal article (peer-reviewed)abstract
- In moist air or by contact with water during washing, KOs2O6 absorbs water molecules into the structure to produce KOs2O6·nH2O, 0 < n < 0.1. This water is reversibly lost on heating above ∼430 K in flowing or static gas environments. Variable temperature powder neutron and X-ray diffraction show that an increase in lattice parameter occurs when water enters the pyrochlore structure and the water molecules are located in the α cages displacing a portion of the potassium ions to adjacent sites. On removing water the lattice parameter and structure revert to those of the normal β-pyrochlore crystallographic description. Hydration has the effect of reducing the onset of superconducting behavior from a critical temperature of 10.25 K in fully dry KOs2O6 to 9.75 K in KOs2O6·0.1H2O.
