Abstract
We use dynamical local-field corrections to study the plasmon dispersion an d damping in double-layer electron systems. The wave vector and frequency-d ependent local-fields describing the exchange-correlation effects are obtai ned within the quantum version of self-consistent field approach. The calcu lated plasmon dispersions are modified by the dynamic local-fields at inter mediate wave vectors (i.e. q similar to k(F)) The plasmons are damped outsi de the single-particle excitation region.
