The phonon dispersion relations and the frequency distribution function of chromium have been calculated on the basis of the lattice-dynamical model of Sharma and Joshi. The frequency distribution has been computed with the help of the Blackman root-sampling technique for a discrete subdivision in the reciprocal space. The frequency distribution function thus computed has been employed for the calculation of the lattice specific heat and the temperature variation of the Debye-Waller factor of chromium. The theoretical results show a reasonable agreement with the experimental data.
