Abstract
Earlier measurements of the thermal conductivity of solid helium (Webb, Wilkinson and Wilks 1952) have been extended to higher densities by using pressures up to 1800 atmospheres. Values of the conductivity are now available for densities from 0·19 to 0·35 g/cm3, corresponding to a range of Debye characteristic temperatures (24 ° to 90°) which is sufficient to cause the measured conductivities at a given temperature to vary by a factor of over 300. Below a density of 0 ·28g/cm3 the present results are in substantial agreement with the discussion given previously; at higher densities the results are irregular.Keywords
