    Notes: [Auszug] It was discovered some time ago1 that when heat flowed in helium II down a narrow capillary or through a tube filled with powder, liquid was forced up the tube in the oppo­site direction. It was con­sidered at the time that the phenomenon, which has been called the ‘fountain ...

    Notes: [Auszug] THE properties of liquid helium can best be considered under two headings: (a) properties in thermal equilibrium, (b) transport effects. The equilibrium properties, which have been the subject of many careful investigations in Leyden and elsewhere, may be regarded as fairly well established. These ...

    Notes: [Auszug] RECENT measurements on the flow of liquid helium II through capillaries have yielded very varied results. We reported earlier1 that the flow through long capillaries bore no relation to a normal laminar or turbulent condition of the liquid, and that the velocity depended only ...

    Notes: [Auszug] A SURVEY of the various properties of liquid helium II has prompted us to investigate its viscosity more carefully. One of us1 had previously deduced an upper limit of 10−5 C.G.S. units for the viscosity of helium II by measuring the damping of an ...

    Notes: [Auszug] IT was found by Rollin1 and by Keesom and Keesom2 that liquid helium II shows an extra-ordinarily high heat conductivity, of the order of 190 cal./deg.cm.sec. We have measured the heat conductivity with the following method, which is essentially a combination of a ...

    Notes: [Auszug] DURING an investigation of the thermal coupling between the ionic magnets and the lattice vibrations of paramagnetic salts in the neighbourhood of the absolute zero, we have made some resistance measurements in the temperature range below 1° K. The resistance measured consisted of a specimen of ...

    Notes: [Auszug] SINCE publishing the preliminary measurements on thermal conduction in liquid helium II1 which showed a variation of conductivity with temperature gradient, further data have been collected concerning the phenomenon. It was noted that the conductivity appeared to increase ...
