Abstract
The specific heats of lithium fluoride, sodium chloride and zinc sulphide have been measured within the temperature range 2°k to 30°k using a calorimeter of a novel type, upon which the crystal specimens were stuck with silicone grease. Ideally, these three substances have only a lattice contribution to their specific heats so that a direct comparison of the results with the theoretical predictions of the lattice theory of specific heats is possible. Good agreement between theory and experiment is found. The existence of a ‘T 3’ region extending up to a temperature of about 20°k is shown clearly in the case of lithium fluoride.Keywords
