dc.description.abstractAshcroft model potential has been used to compute phonon dispersion relations along the three principal symmetry directions, i.e. [k00], [kk0] and [kkk] for α-iron and barium. The computed phonons gave a reasonable agreement with the experimental ones in all the three principal summetry directions expect for the T2 branch in [KK0] direction where the present study failed to reproduce the experimental findings.en
