Calculated Lattice Specific Heats for Seven bcc Elements

A brief review is given of the method by which the author has obtained frequency spectra for a Born-von K\'arm\'an central force model for bcc elements, and of the method in which these spectra are utilized to calculate specific heats. Specific heats have been calculated for the elements lithium, sodium, potassium, iron, tungsten, vanadium, and molybdenum, from the measured elastic constants reported by others. The corresponding Debye characteristic temperature Θ as a function of absolute temperature is shown on a graph for each element along with the experimental low-temperature values obtained by others. An upper limit to the temperature range for which de Launay's method for finding Θ(T) is valid, is given for each element.
