The lattice dynamics of metallic silver has been studied by assuming silver ions embedded in a uniform sea of electrons. The entire interaction has been divided into three, coulombian, repulsive and electron-ion part. The coulombian coupling coefficients have been taken directly from the work of Kellermann. The repulsive and the electron-ion part has been calculated in the manner given by Dayal and Srivastava, and Sharma and Joshi. The effect of the volume forces has been included in the manner of Dayal and Tripathi. The first Brillouin zone has been divided into 10×10×10 points and the secular determinant has been solved for the 48 non-equivalent points. The phonon dispersion curves in the [100] and [111] directions and the theoretical and experimented Debye temperature θ versus T curves have been plotted. The agreement between the theory and the experiment for the latter is found to be reasonable.
