In a typical thermoluminescence experiment, a sample rests on a metallic strip which is heated in a controlled fashion so that the strip temperature rises linearly with time. Thermal contact is improved by the use of an inert exchange gas, usually ar

For pt.I see ibid., vol.26, p.843 (1993). This is the second of a linked pair of papers on the subject of thermoluminescence experiments; it is primarily about calculational models, while the first paper describes experimental results. In a typical t

In the twelve months following the announcement of the UK pit closure programme in October 1992, 22,500 miners were made redundant. In 1994 we undertook a cross-sectional survey to determine whether the mental and physical health of men who had been

Previous experiments have shown that at low temperatures the acoustic impedance of liquid 3 He under the saturated vapour pressure rises by about 10% below about 0.092 °K. This rise is predicted by Landau’s theory of a Fermi liquid. It comes about

Measurements have been made of the viscosity of liquid 3He under its saturated vapour pressure in the temperature range 0•14—2•1°K. In the experiments, a polished cylinder of quartz oscillates in the liquid in its fundamental elastic torsional

We have made detailed measurements of the effective viscosity of dilute ${\mathrm{He}}^{3}$-${\mathrm{He}}^{4}$ solutions between 20 mK and 1 K, by observation of the damping of torsional oscillations of a quartz crystal. The results are strikingly d

Recently results were reported’ from this laboratory on the effective viscosity of dilute mixtures (X3 < 10%) between 20 m°K and 1°K. In the present work we have extended the ranges of concentration up to X3 = 100% and of temperature up to 2°K s

Temperatures have been derived from measurements of frequency of a tuned circuit, the inductance of which encloses a quantity of paramagnetic salt. The expected linear variation of frequency with 1/T was observed (i) between 4° K and 0.1° K, using
