CHARACTERISTIC TEMPERATURES OF CUBIC METALS

An approximation is developed for the determination of the characteristic Debye temperatures of cubic crystals. This method yields results more accurate than those obtained by Bhatia and Tauber using Houston's three-term formula and slightly more accurate than those obtained with the more recent six-term formula of Betts, Bhatia, and Wyman, and also provides a means of estimating the accuracy of these formulae.
