Abstract
Temperature dependence of the anharmonic Debye-Waller factor for some cubic metals are calculated by employing our recent dynamical model. Willis anharmonic approach has been followed to estimate the effect of anharmonic terms in the crystal potential. A comparative study of the computed values and the experimental data in terms of the Debye-Waller temperature parameter Y and the X-ray Debye temperature \(\varTheta_{M}\), reveal the fact that the anharmonic consideration in the crystal potential has greatly improved the results compared with those due to the harmonic and quasi-harmonic approximations.
