Abstract : The temperature dependence of the Debye parameter of tungsten has been calculated with two modifications incorporated into the original Debye theory of solids. These modifications are: (1) the assumption of a common cutoff wavelength for the elastic waves, and (2) a sinusoidal dispersion relation between the wavelength and the frequency which leads to a frequency dependence of the wave velocities. This model yields results for the Debye parameter which are in accord with experimental measurements. (Author)
