Abstract
The mode Gruneisen parameters of Na1Si136 silicon clathrates are determined from Raman-scattering experiments. They are compared to two recent theoret ical calculations using the tight-binding density-matrix method and local-d ensity approximation. This last method is shown to provide better agreement with the experimental results. [S0163-1829(99)05346-1].
