THE recently published measurements1 on some properties of condensed helium, in conjunction with the facts known from the work of Keesom and his co-workers2, allow us to draw some conclusions on the behaviour of helium at very low temperatures. 

Fifty Years of Superfluid Helium

An account is given in terms suitable for a general audience of the discovery of superfluid helium and of the way in which an understanding of this strange liquid has developed over the past half

The Thermal Conductivity of Liquid Helium I

The thermal conductivity of liquid helium has been measured between 22 and 4° K It is found to increase with temperature over the whole range and shows no sign of anomalous behaviour just above the

The thermal conductivity of condensed helium

At low temperatures the thermal conductivity of a condensed phase is very sensitive to structure, and the various phases of condensed helium exhibit a wide range of behavior. The two stable isotopes,

The viscosity of liquid helium has been measured with a flow method between 2 and 5° K . The coefficient of viscosity decreases with decreasing temperature over the whole range. A particularly

Density and Compressibility of Solid Hydrogen and Deuterium at 4·2° K.

IT has been shown by Bennewitz and Simon1 that the influence of zero-point energy on the properties of a condensed substance is very great for substances of low boiling point. The effect is most

Abstract The internal energy and molar volume at absolute zero and the characteristic temperature of the inert gas solids, together with solid hydrogen and deuterium, are calculated taking account of

XLIII. The ideal crystal at absolute zero

Abstract Theoretical expressions for the internal energy, equilibrium volume, and elastic constants of the rare gas solids at absolute zero are derived, using a recently proposed approximation for

The negative coefficient of thermal expansion of He ii is shown to be a consequence of the disordering process which takes place as the temperature rises. The conclusion is reached that the thermal
