We use dynamical local-field corrections to study the plasmon
dispersion and damping in double-layer electron systems. The wave
vector and frequency-dependent local-fields describing the
exchange-correlation effects are obtained within the quantum
version of self-consistent field approach. The calculated plasmon
dispersions are modified by the dynamic local-fields at
intermediate wave vectors (i.e.q ∼ kF). The plasmons are
damped outside the single-particle excitation region.
