Abstract
The phonon dispersion curves of silver have been measured in the main symmetry directions at room temperature by coherent inelastic scattering of thermal neutrons using a correlation technique.
The experimental results have been analyzed with parametrized expressions which have been derived from interatomic model potentials. With the Born-von Karman force constant model thermodynamic properties of silver could be calculated in good agreement with experimental results. Through the use of electron-ion model potentials the lattice dynamics of silver was correlated with its electronic properties. The results for some of those properties are compared with corresponding experimental values.
