In the former case the calculations are made based on the assumption of a rigid background for the conduction electrons, and extended to the metal-rich concentration range by taking into account the polarisability of the electron gas. The most interesting prediction of our analysis is that sound waves should be overdamped below a critical wavenumber for a certain range of concentrations in the salt-rich region of metal-salt solutions.Read More
