摘要：

Electron-acoustic waves have strong linear Landau damping, but are observed as non-linear BGK modes in experiments with pure electron plasmas. The waves have phase velocity v(phi) approximate to 1.3 (v) over bar in agreement with theory, and the longest wavelength BGK states exhibit only relatively weak damping. Shorter wavelength modes exhibit a strong decay instability which can be experimentally controlled.
