Abstract
Nonlinear damping of a broad-band spectrum of plasma waves has been observed. Frequencies lower than the spectrum are growing from background noise. A shift of the entire spectrum towards lower frequencies results. The evolution of the spectrum is in good agreement with the predictions of weak-turbulence theory. Measurements of the electron velocity distribution are presented.Keywords
