Abstract
Intraband pair excitation and plasmon spectra of nonequilibrium plasma s are analyzed using the dynamic dielectric function in the random-pha se approximation. Nonequilibrium conditions are identified for which t he Landau damping of acoustic plasmons vanishes. This acoustic-plasmon undamping is discussed for two-component plasmas and for one-componen t plasmas with a double-peaked distribution in momentum space.
