| Résumé : | Using the microscopic hydrodynamic-mode theory recently developed by the author, we obtain an exact expression for the long-wavelength, low-frequency behaviour of the kinetic-energy density fluctuations. We also show that this expression furnishes a good understanding of the recent Rahman computer calculation of a sodium-like liquid system at the wavelength λ=27 A ̊. © 1972. |
