Diffusion of tritium from lithium fluoride
physica status solidi (b), 1966AbstractThe release of tritium from neutron irradiated LiF single crystals (5.4 × 1016 nvt, at approximately 300 °C) follows the relation D = 6 exp (−38800/RT) cm2s−1 between 500 °C and the melting point. Volume diffusion kinetics are obtained from isothermal experiments. The tritium diffusion is found to be essentially independent of the neutron dose (

Voltammetry of iron in molten lithium fluoride-potassium fluoride-sodium fluoride
Journal of Electroanalytical Chemistry (1959), 1963Abstract The voltammetry of iron (II) in molten LiF—NaF—KF was investigated over the temperature range 470–545‡. The current—voltage curves were recorded using a controlled-potential polarograph and a stationary platinum micro-electrode coupled with a platinum quasi-reference electrode.

Charged dislocations in lithium fluoride
Philosophical Magazine, 1960Abstract The application of strong electrostatic fields to bent LiF crystals producod small motions (0·1 to 6 A) of the bends which were analysed in terms of the motion of charged dislocations. The charge on the dislocation core was positive and of the order of 10−4 to 10−3 e.s.u./cm, and it presumably arose from the inequality of the free energies of ...

Strength of lithium fluoride whiskers
Journal of Physics and Chemistry of Solids, 1958A procedure is described for growing lithium fluoride whiskers. Stress/ strain curves in tension were measured on a few lithium fluoride whiskers using a tensile machine. Mechanical properties of the whiskers closely lithium fluoride crystals are discussed.

A Lithium Fluoride Thermoluminescent Dosimeter
1965Report in the literature of the use of a thermoluminescent dosimeter using Lithium Fluoride have been most encouraging particularly in view of the nearness of the atomic number of the detecting material to that of tissue. The reported size of a satisfactory dosimeter too added considerably to its promise as a clinical instrument.

Electron scattering by lithium fluoride
Journal of Physics B: Atomic and Molecular Physics, 1978Calculations of elastic and rotational excitation cross sections for electron scattering by LiF are presented. A model potential is used and the cross sections computed using the close-coupling and a number of other theoretical methods. The accuracy of the various methods is assessed and a comparison with experimental data shows close agreement at an ...
