Oxygen Transport in Vapor-Deposited Tin-Doped Indium Oxide Films (Diffusion, Electrochemical)
… in the films. Finally, thermogravimetric and x-ray lattice parameter measurements were made on Sn-doped In(,2)O(,3) powder to provide additional support for the defect model.

Phase separation in solid mixtures of helium-3 and helium-4
… pressure from measurements of changes in the x-ray lattice parameter and peak shape. A new rigid tail dilution refrigerator cryostat is used to study 3 He-4He crystals with 3He concentrations of 0.10,0.20,0.30,0.45,0.60 and 0.70, and melting pressures between 3.0 and 4.3 MPa. The phase …

Thermal vacancies in solid helium-3
… of the tem3 perature dependence of the x-ray lattice parameter. Bcc He 3 was studied for molar volumes ranging from 20.3 to 24.8 cm ; mole for which the melting temperatures range from 2.36 to 0.435K. It was found to contain about 0.5% thermal vacancies at melting, essentially independent …

Thermal vacancies and phase separation in bcc mixtures of helium-3 and helium-4
… of the temperature dependence of the x-ray lattice parameter. A new x-ray diffractometer-position sensitive detector system is used to make measurements of the absolute lattice parameter of the helium crystals with an accuracy of 300 ppm, and measurements of changes in lattice parameter …

Equilibrium vacancy concentration measurements and thermal properties of solid krypton
Simultaneous length and x-ray lattice parameter expansion measurements have been made on three 6 mm diam cylindrical specimens of 99.995% purity krypton. The specimens were prepared and held unconstrained in a rigid-tail cryostat in which specimen temperatures could be precisely controlled. The …
