Abstract

We present the results of experimental investigations of linear and nonlinear waves on the charged surface of liquid hydrogen. The experiments were performed in a cylindrical experimental cell. It is found that the spectrum of linear waves is softened when the intensity of electric field increases. Weak turbulence in the system of capillary waves on the charged surface of liquid hydrogen was studied. The formation of the Kolmogorov cascade was observed in the frequency interval from ~ 100 Hz to ~ 10 kHz. It is found that the correlation function of the surface deviation from the equilibrium flat state can be described by power function with the index m=-3.7±0.3 for the surface excited by harmonic force at one frequency and with m=-3±0.3 for two frequencies case. The results are in qualitative agreement with theoretical predictions.
