Abstract
We report about an electron energy-loss study on the dispersion of the charge-carrier plasmon in the charge-density-wave system $2H{\text{-TaSe}}_{2}$ above and below the metal-insulator transition. In both cases we find a negative slope, which is in remarkable contrast to the traditional prediction for metals based on the random-phase approximation. Possible scenarios for this intriguing phenomenon are discussed.
